a few modifications to these files:
- applications/present3D/Cluster.cpp
- src/osgDB/FileUtils.cpp
The changes are needed to fix a few platform specific things such as the
absence of stat64, int/socklen_t differences, etc... and are in the same
line as Linux, Apple and FreeBSD specific checks.
I have attached the modified files; the original patches to 3.0.1 are
also visible here if you find it more convenient:

With these changes, osg 3.0.1 is able to be built and packaged on DragonFly
whereas it previously failed to compile."
This is because Qt auto repeats keyboard events, so multiple calls are made to GLWidget::keyPressEvent and GLWidget::keyReleaseEvent by Qt, and subsequently translated to OSG events.
The way to solve this is ignoring key released auto repeated events (see http://qt-project.org/doc/qt-4.8/qkeyevent.html#isAutoRepeat), so multiple KEYDOWN events are fired, but only one KEYUP.
I attach a modified osgQt/GraphicsWindowQt.cpp with this change."
New methods osg::Geometry::containsDeprecatedData() and osg::Geometry::fixDeprecatedData() provide a means for converting geometries that still use the array indices and BIND_PER_PRIMITIVE across to complient
versions.
Cleaned up the rest of the OSG where use of array indices and BIND_PER_PRIMITIVE were accessed or used.
It's
return osg::Image::computeImageSizeInBytes(width, height, depth, packing, slice_packing, image_packing);
but I think it should be
return osg::Image::computeImageSizeInBytes(width, height, depth, pixelFormat, pixelType, packing, slice_packing, image_packing);"
GeometryNew is only temporary and will be renamed to Geometry on the completion of refactoring work and feedback from community.
Ported osggeometry across to use GeometryNew.
The API has changed quite a bit, so lots of changes had to be made in the osg readerwriter. The preious version of the FBX SDK (2013.3) already deprecated a lot of the names and functions. The code I submit now still compiles against 2013.3 (possibly needs a #define FBX_NEW_API). Not sure if that's useful, but it might ease the transition."
a change in version 5.0.0 required a call to the fuction "DGifOpen" to pass an int ref for an error code.
My fix ignores the error, just fixes the compile."
The plugin does not support images without alpha channel for opacity
This seems to indicate that the check for alpha should be against the opacity map. I've attached the updated file.
"
The following change to State.cpp fixes the case where textures in a stateset along with a compute shader program did not make those textures available to the shader, since it got evaluated before the texture bind(s)."
Note from Robert, Michael only change State::apply(StateSet*) so I also applied the same reversal in apply of texutre modes/state into the State::apply() method for consistency.
I looked into the "State::applyShaderComposition" method and noticed that it will print debug information to the osg::INFO stream. I commented that line out and the performance drop was gone.
I'm not sure if the printing was accidentally left in or is meant to be enabled. I've modified the function to only call the print function if INFO logging is enabled. I've attached the change."
