ea9f479674 Attempt to fix broken DLL exports from osgDB 
Only export the osgDB method implementations, instead of the entire
class, and hence avoid exporting symbols from the base class, which
then conflict with other compilation units when linking.

This avoids the need for /FORCE:MULTIPLE linker option with MSVC.

da47f8a156 Adds an indexMesh option to disable mesh reindexation 
This mainly breaks gles/osgjs when stripifying a MorphGeometry. It also
usually doesn't make sense to reindex an already indexed mesh.

ed7d49c5d2 CleanUpOperation added to Viewer 
Sometimes there is need to do cleanup with valid graphic contexts
before closing these contexts. The added operation runs a graphics
operation on each context before closing them.

One usage case for this functionality to support usage of Wayland and X11 in the same version of the osgViewer.

As part of the new functionality there is now a osg::GraphicsContext::Traits::windowingSystemPreferrence string
that default to empty, but if defined will ensure that a specific WindowingSystemInterface is utilized when
you do a generic call like osg::createGraphicsContext().

Also implemented is standard proxy object for registering the new contexts and removing them automatically, and
declaration of standard graphicswindow_name() C entry point to help with static build linking.

5d03bb9a2b From Jannik Heller, "This submission fixes a stuttering issue that may occur when occlusion query nodes are in view. The problem is that OSG retrieves the occlusion query result without first checking if it's available (GL_QUERY_RESULT_AVAILABLE). Thus, the driver has to sync with the GPU i.e. wait for all queued draw calls to complete. This is particularly bad in V-Synced situations where the driver may be using multi frame queueing techniques - coupled with the fact that OSG only runs an occlusion query every 5th frame, results in very unpleasant stuttering in some situations. 
The change I made is to check GL_QUERY_RESULT_AVAILABLE before retrieving the query, to ensure that there won't be a stall. If the query result is not available yet, we'll leave it alone and try again in the next frame.

Had to make a few more changes than I'd liked, mostly because the TestResult mechanism wasn't designed for holding on to query objects for more than one frame. As well, I'm thinking that RetrieveQueriesCallback and ClearQueriesCallback could be merged together, if we wanted to go for more refactoring. For though now my strategy is to make as little changes as possible. Let me know what you think of the patch."

be98c884bd From Ognjen Kostic, "Some android phones have no support for OES_element_index_uint extension that is required if glDrawElements is to be called with GL_UNSIGNED_INT for element type. 
In OSG 3.4, osgText::Text( ::_quadIndices) uses DrawElementsUInt that will fail on these devices and no text will appear - tested on Samsung Galaxy Trend 2 SM-G313HN.

When DrawElementsUInt is replaced with DrawElementsUShort it works, although I'm not sure if this can cause other problems with some fonts.

Fix:
- In include\osgText\Text, line 316:
        replace: "osg::ref_ptr< osg::DrawElementsUInt > _quadIndices;"
        with:    "osg::ref_ptr< osg::DrawElementsUShort > _quadIndices;"

- In src\osgText\Text.cpp, line 2094:
        replace: "_quadIndices = new DrawElementsUInt(PrimitiveSet::TRIANGLES);"
        with:    "_quadIndices = new DrawElementsUShort(PrimitiveSet::TRIANGLES);"

Font::getKerning(...), Font::getGlyph3D(...) doesn't ask for a font resolution so it uses the last font resolution requested by Font:: getGlyph(...).
This can leads to different results depending of the precedent call to Font::getGlyph(...).
See http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2016-January/271952.html for more infos.

This fix adds a font resolution parameter to Font::getKerning(...), Font::getGlyph3D(...) and to the font implementations.

Robert Osfield
dd996a3289 Introduced CMake option OSG_PROVIDE_READFILE option that defaults to ON, but when switched to OFF disables the building of the osgDB::read*File() methods, 
forcing users to use osgDB::readRef*File() methods.  The later is preferable as it closes a potential threading bug when using paging databases in conjunction
with the osgDB::Registry Object Cache.  This threading bug occurs when one thread gets an object from the Cache via an osgDB::read*File() call where only
a pointer to the object is passed back, so taking a reference to the object is delayed till it gets reassigned to a ref_ptr<>, but at the same time another
thread calls a flush of the Object Cache deleting this object as it's referenceCount is now zero.  Using osgDB::readREf*File() makes sure the a ref_ptr<> is
passed back and the referenceCount never goes to zero.

To ensure the OSG builds when OSG_PROVIDE_READFILE is to OFF the many cases of osgDB::read*File() usage had to be replaced with a ref_ptr<> osgDB::readRef*File()
usage.  The avoid this change causing lots of other client code to be rewritten to handle the use of ref_ptr<> in place of C pointer I introduced a serious of
templte methods in various class to adapt ref_ptr<> to the underly C pointer to be passed to old OSG API's, example of this is found in include/osg/Group:

    bool addChild(Node* child); // old method which can only be used with a Node*

    tempalte<class T> bool addChild(const osg::ref_ptr<T>& child) { return addChild(child.get()); } // adapter template method

These changes together cover 149 modified files, so it's a large submission. This extent of changes are warrent to make use of the Object Cache
and multi-threaded loaded more robust.

161246d864 Refactored the GL object deletion management to use new osg::GraphicsObjectManager/GLObjectManager base classes, and osg::ContextData container. 
This approach unifies much of the code handling the clean up of OpenGL graphics data, avoids lots of local mutexes and static variables that were previously required,
and enables the clean up scheme to be easily extended by users providing their own GraphicsObjectManager subclasses.

34794c5c27 From Laurens Voerman, "I found that using an ImageSequence with mode PAGE_AND_DISCARD_USED_IMAGES triggers the (3) imageThreads to run and never stop, even when no more work is to be done. This is due to a bug in the stop condition currently setting the thread to stop and wait for a signal only when no work needs to be done AND the databasepager is paused. 
It should stop and wait for a signal on either of those two. Due to a few logical inversions it boils down to replacing || with &&

OLD _block->set((!_requestList.empty() || !_pager->_databasePagerThreadPaused));
NEW _block->set((!_requestList.empty() && !_pager->_databasePagerThreadPaused));//release the threads to run IF (work_to_be_done && not_paused)

This bug is present since svn rev 8663 (just before 2.6.0 release)

While testing the build with OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION=OFF I found a compile error in GlyphGeometry.cpp that was entirely unrelated to the changes I've made. The fix is included in the patch.

16b19a0c30 Refactored AntiSquish::computeUnSquishedMatrix() method to use the parent node path of the AntiSquish node 
to compute the required matrix rather than using the NodePath provided by the NodeVistor. This is required
as in osg::computeLocalToWorld() usage case the NodeVisitor pointer is NULL, so the correct matrix isn't possible to compute.

ec6edf535d From Miha Ravselj, "Regarding previous submission it was only partial solution. After further testing I found similar bug also in ClearNode serializer. 
//GLbitfield mask = GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT;
This line was problematic since it produced incorrect result when let's say COLOR flag is serialized
it should be null as in Camera serializer or in a proposed BitFlagsSerializer


This line of code caused that whenever only GL_COLOR_BUFFER_BIT bit was written and on value read GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT was restored instead of GL_COLOR_BUFFER_BIT only.

//GLbitfield mask = 0; //this resolves the issue same as in camera
Also same bit-wise comparison bug was also present in write method.
-------------------------------------------------------------------------------------

As you can see there are total 3 bit mask serializers in OSG and all 3 had bugs so I decided to add ADD_BITFLAGS_SERIALIZER and replace USER serializers in osg::Camera, osg::ClearNode and osgText::TextBase. I have made sure that bitflags serializer does not break backwards-compatibility since it uses same code as user serializer does in all 3 cases. (see tester.cpp on how compatibility test was performed)"

1d9e7f144b From Michael McDonnel, "The tessellation shader example has a small bug.The middle of the 
geometry is clipped as soon as it is tessellated. The clipping is
probably caused by rounding errors because it is only in one spot. The
clipping disappears when the camera is moved, and reappears when it is
moved back. Expanding the the bounding box fixed the clipping bug."

Tweaked by Robert Osfield to expand it to a -1 to 1 unit box.
Actual clipping bug is not due to rounding errors but the shaders creating vertices outside the bounding box of the original input vertices

58c47e9842 From Marc Helbling, "please find enclosed a submission that should improve the VertexAccessOrderVisitor (pre-transform) optimizer: 
* it sorts primitives to keep "more complex" primitives first; maybe you'll prefer to have this as an option (but usually it should make more sense to pre-transform triangles before e.g. lines)
* currently, the visitor rely on TriangleIndexFunctor and does not take care of points and lines (see https://github.com/openscenegraph/osg/blob/master/include/osg/TriangleIndexFunctor#L124-130). This can lead to issues e.g. if you store the wireframe lines along with some triangles: the triangles will be reindexed but not the line. I've therefore added osg/include/TriangleLinePointIndexFunctor to index triangles, lines and points and derived VertexReorder from this class.
* to avoid issues, shared arrays are duplicated. However, in some cases (e.g. an UV channel shared in the geometry only) this is not required. I'm adding a SharedArrayOptimizer to optimize this: it looks for duplicated UVs before the array duplication and deduplicate arrays after.

Note that:
* as the name suggest, it only works for triangle strips but could probably be easily extended to quads
* the resulting primitive is not highly optimized; we could probably sort the strips in order to minimize the number of primitive restart
* as we may merge DrawElementsUInt and DrawElementUShort, the code will only generate DrawElementsUInt"

4c5a1885d2 From PawelKsiezopolski, "This submission contains a new example for OSG : a geometry instancing rendering 
algorithm consisting of two consequent phases :

- first phase is a GLSL shader performing object culling and LOD picking ( a culling shader ).
  Every culled object is represented as GL_POINT in the input osg::Geometry.
  The output of the culling shader is a set of object LODs that need to be rendered.
  The output is stored in texture buffer objects. No pixel is drawn to the screen
  because GL_RASTERIZER_DISCARD mode is used.

- second phase draws osg::Geometry containing merged LODs using glDrawArraysIndirect()
  function. Information about quantity of instances to render, its positions and other
  parameters is sourced from texture buffer objects filled in the first phase.

The example uses various OpenGL 4.2 features such as texture buffer objects,
atomic counters, image units and functions defined in GL_ARB_shader_image_load_store
extension to achieve its goal and thus will not work on graphic cards with older OpenGL
versions.

The example was tested on Linux and Windows with NVidia 570 and 580 cards.
The tests on AMD cards were not conducted ( due to lack of it ).
The tests were performed using OSG revision 14088.

The main advantages of this rendering method :
- instanced rendering capable of drawing thousands of different objects with
  almost no CPU intervention  ( cull and draw times are close to 0 ms ).
- input objects may be sourced from any OSG graph ( for example - information about
  object points may be stored in a PagedLOD graph. This way we may cover the whole
  countries with trees, buildings and other objects ).
  Furthermore if we create osgDB plugins that generate data on the fly, we may
  generate information for every grass blade for that country.
- every object may have its own parameters and thus may be distinct from other objects
  of the same type.
- relatively low memory footprint ( single object information is stored in a few
  vertex attributes ).
- no GPU->CPU roundtrip typical for such methods ( method uses atomic counters
  and glDrawArraysIndirect() function instead of OpenGL queries. This way
  information about quantity of rendered objects never goes back to CPU.
  The typical GPU->CPU roundtrip cost is about 2 ms ).
- this example also shows how to render dynamic objects ( objects that may change
  its position ) with moving parts ( like car wheels or airplane propellers ) .
  The obvious extension to that dynamic method would be the animated crowd rendering.
- rendered objects may be easily replaced ( there is no need to process the whole
  OSG graphs, because these graphs store only positional information ).

The main disadvantages of a method :
- the maximum quantity of objects to render must be known beforehand
  ( because texture buffer objects holding data between phases have constant size ).
- OSG statistics are flawed ( they don't know anymore how many objects are drawn ).
- osgUtil::Intersection does not work

Example application may be used to make some performance tests, so below you
will find some extended parameter description :
--skip-dynamic       - skip rendering of dynamic objects if you only want to
                       observe static object statistics
--skip-static        - the same for static objects
--dynamic-area-size  - size of the area for dynamic rendering. Default = 1000 meters
                       ( square 1000m x 1000m ). Along with density defines
                       how many dynamic objects is there in the example.
--static-area-size   - the same for static objects. Default = 2000 meters
                       ( square 2000m x 2000m ).

Example application defines some parameters (density, LOD ranges, object's triangle count).
You may manipulate its values using below described modifiers:
--density-modifier   - density modifier in percent. Default = 100%.
                       Density ( along with LOD ranges ) defines maximum
                       quantity of rendered objects. registerType() function
                       accepts maximum density ( in objects per square kilometer )
                       as its parameter.
--lod-modifier       - defines the LOD ranges. Default = 100%.
--triangle-modifier  - defines the number of triangles in finally rendered objects.
                       Default = 100 %.
--instances-per-cell - for static rendering the application builds OSG graph using
                       InstanceCell class ( this class is a modified version of Cell class
                       from osgforest example - it builds simple quadtree from a list
                       of static instances ). This parameter defines maximum number
                       of instances in a single osg::Group in quadtree.
                       If, for example, you modify it to value=100, you will see
                       really big cull time in OSG statistics ( because resulting
                       tree generated by InstanceCell will be very deep ).
                       Default value = 4096 .
--export-objects     - write object geometries and quadtree of instances to osgt files
                       for later analysis.
--use-multi-draw     - use glMultiDrawArraysIndirect() instead of glDrawArraysIndirect() in a
                       draw shader. Thanks to this we may render all ( different ) objects
                       using only one draw call. Requires OpenGL version 4.3 and some more
                       work from me, because now it does not work ( probably I implemented
                       it wrong, or Windows NVidia driver has errors, because it hangs
                       the apllication at the moment ).

This application is inspired by Daniel Rákos work : "GPU based dynamic geometry LOD" that
may be found under this address : http://rastergrid.com/blog/2010/10/gpu-based-dynamic-geometry-lod/
There are however some differences :
- Daniel Rákos uses GL queries to count objects to render, while this example
  uses atomic counters ( no GPU->CPU roundtrip )
- this example does not use transform feedback buffers to store intermediate data
  ( it uses texture buffer objects instead ).
- I use only the vertex shader to cull objects, whereas Daniel Rákos uses vertex shader
  and geometry shader ( because only geometry shader can send more than one primitive
  to transform feedback buffers ).
- objects in the example are drawn using glDrawArraysIndirect() function,
  instead of glDrawElementsInstanced().

Finally there are some things to consider/discuss  :
- the whole algorithm exploits nice OpenGL feature that any GL buffer
  may be bound as any type of buffer ( in our example a buffer is once bound
  as a texture buffer object, and later is bound as GL_DRAW_INDIRECT_BUFFER ).
  osg::TextureBuffer class has one handy method to do that trick ( bindBufferAs() ),
  and new primitive sets use osg::TextureBuffer as input.
  For now I added new primitive sets to example ( DrawArraysIndirect and
  MultiDrawArraysIndirect defined in examples/osggpucull/DrawIndirectPrimitiveSet.h ),
  but if Robert will accept its current implementations ( I mean - primitive
  sets that have osg::TextureBuffer in constructor ), I may add it to
  osg/include/PrimitiveSet header.
- I used BufferTemplate class writen and published by Aurelien in submission forum
  some time ago. For some reason this class never got into osg/include, but is
  really needed during creation of UBOs, TBOs, and possibly SSBOs in the future.
  I added std::vector specialization to that template class.
- I needed to create similar osg::Geometries with variable number of vertices
  ( to create different LODs in my example ). For this reason I've written
  some code allowing me to create osg::Geometries from osg::Shape descendants.
  This code may be found in ShapeToGeometry.* files. Examples of use are in
  osggpucull.cpp . The question is : should this code stay in example, or should
  it be moved to osgUtil ?
- this remark is important for NVidia cards on Linux and Windows : if
  you have "Sync to VBlank" turned ON in nvidia-settings and you want to see
  real GPU times in OSG statistics window, you must set the power management
  settings to "Prefer maximum performance", because when "Adaptive mode" is used,
  the graphic card's clock may be slowed down by the driver during program execution
  ( On Linux when OpenGL application starts in adaptive mode, clock should work
  as fast as possible, but after one minute of program execution, the clock slows down ).
  This happens when GPU time in OSG statistics window is shorter than 3 ms.

f8c4ad4b90 From Pjotr Svetachov, "I was experimenting with VBO's to try to get them on par with display 
lists when drawing lots of batches and noticed that my program
generated a lot of unneeded glClientActiveTexture calls. Digging
deeper I found out it came from State::disableTexCoordPointer where
the function would call glClientActiveTexture but not
glDisableClientState because the geometry didn't have texture
coordinates for that channel. This is because in our scene there are
some geometries that have move than one uv channels making
State::_texCoordArrayList grow. Then the method
State::applyDisablingOfVertexAttributes() will call
disableTexCoordPointer multiple times.

I rearrange the method a little to combat this. Now the logic has the
same ordering as disableTexCoordPointersAboveAndIncluding which
already combats this."

4c1fd06252 Added osg::SyncSwapBuffersCallback to include/osg/GraphicsContext and support for enabling it to include/osg/DisplaySettings, and to the Viewer/CompositeViewer::realize() methods. 
To enable the sync of swap buffers set the env var OSG_SYNC_SWAP_BUFFERS to ON or 1, to switch off set to OFF or 0.

One can also use the --sync command line option for application that pass on command line options to the osg::DisplaySettings::instance().
