Hi Curtis,

Thanks for testing things out.

Potentially we could de-instate the osg::State::dirtyTexCoordPointer()
as there osg::VertexArrayState takes over this functionality, you can
get the current VertexArrayState via
state.getCurrentVertexArrayState().  I removed the functions like
dirtyTexCoordPointer() to help make sure the rest of the OSG doesn't
rely on deprecated methods.  I wasn't expect it to be used widely by
users.  Is there code you had to modify open sourced?  If so could you
point me at it so I can work why it's being used and the way it's
being used.  This might help inform how to adapt things.

For OSG-3.6 it would be ideal to smooth out glitches that end uses are
seeing so any assistance on homing on what the issues are will really
help in this.
