Image format enums needs improvement
|Reported by:||marcusl||Owned by:||unassigned|
Using OSG_I_PF (GL_INTENSITY) yields an error in TextureChunk? on glTexSubImage() as GL_INTENSITY is not a valid format enum for that gl-function.
Also, there is no OSG_A_PF (GL_ALPHA) equivalent, which might be useful?
It's possible to work around these by setting the internal/external format fields in TextureChunk?, but that doesn't feel like a permanent solution.
