[osg-submissions] EXT_texture_integer submission ShaderModel 4.0

[Robert Osfield]

Thanks, the new set of changes look sensible,  so I have gone ahead and merged.

I  had to change the dirty generate mipmap flag to use a
buffered_value<> instead of you bool so that the code will handle
multiple graphics contexts.  I also removed the checking of this flag
from the copy constructors and compare method as this was
inappropriate.

All these changes are now checked in.  I'm planning to change the use
of EXT in the pixel type names across to non EXT versions as future
rev's of OpenGL could these made part of the standard OpenGL, this way
end users won't have to recode things.

Robert.
