It does not like that the prototype of ClipNode::setStateSetModes() differs
from implementation of that function in the constness of the second
parameter.
On SunOS it compiles fine, but I get link errors when the variant that is
declared in the header is referenced.
The attached src/osg/ClipNode.cpp file removes the const qualifier from the
implementation to match exactly the prototype in the header file.
The file is based on revision 7386 as of today.

- GL2Extensions, Program and Program.cpp
Features:
- Support for fragment output binding. (e.g. You can now specify in the fragment shader varying out vec3 fragOut; fragOut = vec3(1,0,1); to write to the fragOut variable. In your program you call glBindFragDataLocation(program, 1, "fragOut") to bind the fragOut variable with the MRT 1 - GL_COLOR_ATTACHMENT1_EXT)
- new methods Program::add/removeBindFragDataLocation Program::getFragDataBindingList
"
- Implementation of integer textures as in EXT_texture_integer
- setBorderColor(Vec4) changed to setBorderColor(Vec4d) to pass double values
as border color. (Probably we have to provide an overloading function to
still support Vec4f ?)
- new method Texture::getInternalFormatType() added. Gives information if the
internal format normalized, float, signed integer or unsigned integer. Can
help people to write better code ;-)

Futher changes to this submission by Robert Osfield, changed the dirty mipmap
flag into a buffer_value<> vector to ensure safe handling of multiple contexts.
local function pointer to avoid compiler warnings related to case void*.
Moved various OSG classes across to using setGLExtensions instead of getGLExtensions,
and changed them to use typedef declarations in the headers rather than casts in
the .cpp.
Updated wrappers
"A new texture class Texture2DArray derived from
Texture extends the osg to support the new
EXT_texture_array extensions. Texture arrays provides
a feature for people interesting in GPGPU programming.
Faetures and changes:
- Full support for layered 2D textures.
- New uniform types were added (sampler2DArray)
- FrameBufferObject implementation were changed to
support attaching of 2D array textures to the
framebuffer
- StateSet was slightly changed to support texture
arrays. NOTE: array textures can not be used in fixed
function pipeline. Thus using the layered texture as a
statemode for a Drawable produce invalid enumerant
OpenGL errors.
- Image class was extended to support handling of
array textures
Tests:
I have used this class as a new feature of my
application. It works for me without problems (Note:
Texture arrays were introduced only for shading
languages and not for fixed function pipelines!!!).
RTT with Texture2DArray works, as I have tested them
as texture targets for a camera with 6 layers/faces
(i.e. replacement for cube maps). I am using the array
textures in shader programming. Array textures can be
attached to the FBO and used as input and as output."
CmakeLists.txt and to the FindPerformer.cmake module.
Under Windows libs are: libpf.lib (we need to add the lib prefix) and
libpfdu-util.lib (libpfdu and libpfutil are compiled into one lib)
We need to add PFROOT to the search path for libs and includes (default
environment variable for Performer path)
And at last we need to put PFROOT/include and PFROOT/include/Performer
as include dir for compiling."
is targeted by a rigid body which is the reason why the .h-file was changed too.
So now there'll be Group as often as possible, otherwise PostitionAttitudeTransform."
Note from Robert Osfield. A couple of lines of code in ConvertToInventor.cpp
would not compile under g++ 4.1.2, so rather than hold back the dev release till
this is resolved I've optional compiled out the problem section.
The #define DISABLE_PROBLEM_COMPILE_SECTIONS is used to compile out the problem
section, this define is add via the CMakeLists.txt file.
GL_LUMINANCE data instead of GL_RGB data. You can easily check with
"osgViewer --image klink1_l.tif".
The bug is in ReaderWriterTIFF.cpp function simage_tiff_load, where
numComponents_ret is incorrectly set to 1 instead of 3 for color mapped
data."
Attached the modified version of MFC_OSG_MDIView.cpp and MFC_OSG_MDIView.h."
Note from Robert Osfield, submission came with wrong header file, so have had
to guess at what it should be, fingers crossed it worn't break windows build... :-)
