selectively set the pixel format for windows that are inherited, following
some discussions on the mailing list last week.
This is implemented through a new traits flag
(setInheritedWindowPixelFormat) with a default state of false (to avoid
breaking existing applications). When set to true, the pixel format of the
inherited window will be set according to the traits specifications.

the osgsimpleviewerQt4 example in my Visual studio solutions... After
looking into it it seems that you cannot have both Qt3 and Qt4
enabled. After modifying the root CMakeLists.txt to use :
FIND_PACKAGE(Qt) which should ask you to choose betwwen Qt3 and Qt4
if you have both
instead of :
FIND_PACKAGE(Qt3)
FIND_PACKAGE(Qt4)
I had the project generated. But then due to the way CMake handles Qt4
I had to modify osgsimpleviewerQt4's CMakeLists.txt to have the binary
link with QtOpengl4. "
setActiveTextureUnit methods of osg::State so they return false if the
texture unit is outside the range of allowable units for the driver.
Currently, the functions would return true even if the units are
invalid. This would cause the osg::State to become out of sync with
the actual driver state, which can cause some bugs in certain cases.
The change I made would verify that the unit passed to
setClientActiveTextureUnit is below GL_MAX_TEXTURE_COORDS, and the
unit passed to setActiveTextureUnit is below
max(GL_MAX_TEXTURE_COORDS,GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS). I
modeled this behavior from the OpenGL docs for these commands which
can be found here:

"
Most of the code is from the osgviewer application, I have took the fullscreen handler and the threading one, and I have just added a fonctionality to be able to change the screen resolution in windowed mode."
"Attached are updates of src/osg/Sequence.spp and include/osg/Sequence.
I've taken _sbegin/_send/_ubegin/_uend and _step our of the include file
and made them local variables in whatever method might need them.
I got rid of the _recalculate method as it was only getting used in
one place.
I also found a cut/paste bug in setMode's START case."
Note from Robert Osfield, Also includes some guards against crashes that was occuring in this new
code when handling empty Sequences.
