While we added OpenGL 4, it seems we missed adding pbo-bound check and the additional range-check (for CPU Buffers) on the new named texture sub-image update functions.
.. also for the named texture initialization/setup functions, e.g. glTextureImage3DEXT ..
commit dad07ad7f7e54c593e58fe3a7ace41bfe4f39b05: Adding missing range- and pbo-bound checks for: - glTextureImage1DEXT - glTextureImage2DEXT - glTextureImage3DEXT - glTextureSubImage1D - glTextureSubImage1DEXT - glTextureSubImage2D - glTextureSubImage2DEXT - glTextureSubImage3D - glTextureSubImage3DEXT
