parameter in osg::Image. To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.
With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU. However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block. The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.
To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row. To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
the type of the virtual function ImageStream::getCurrentTime(), and with this fixing a compile and runtime error.
Changed time variables all to use doubles rather than float to be consist with the change to getCurrentTime().
the required header mathematics.h is not being included explicitly.
I have just included it, and verified that this also works with current
version 0.7, since the header is also available there."
"From David Glenn and Paul Martz. This change adds support for the NO_COLOR bit in the Vertex records' flags field. If NO_COLOR is set, and PACKED_COLOR is not set, the code will now properly default to using the face color at those vertices. See the osg-users thread "Open Flight characteristic not reflected in the current OSG" for more info."

"In consultation with David Glenn, it appears we needed to change a second file to correct how OpenFlight handles transparency when vertices have NO_COLOR. "
functionality when using Terrain::setVerticalScale. This was caused by
the following call sequence resulting in a lockup:
void Terrain::setVerticalScale(float scale)
CALLS dirtyRegisteredTiles();
void Terrain::dirtyRegisteredTiles(int dirtyMask)
SETS LOCK OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
and CALLS (on every tile) setDirtyMask(dirtyMask);
void TerrainTile::setDirtyMask(int dirtyMask)
CALLS _terrain->updateTerrainTileOnNextFrame(this);
void Terrain::updateTerrainTileOnNextFrame(TerrainTile* terrainTile)
SETS LOCK OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
******* PROBLEM - since lock has already been set! ********
The suggested fix submitted changes from using Mutex to ReentrantMutex.
"
You can now set a "intersection mask" and it will be used when looking for intersections.
So you can now easily "hide" some objects from manipulators."
I don’t have access to an OSX or Linux dev machine to make the changes required to the quick time plugin. This plugin will just default to returning 0."

GL_DEPTH_COMPONENT32_OES is not defined for 1.x. I added a #define-guard."
