John Kessenich d6bef9186b Correct textureGather*() extension support:
- add extension behavior and warning message for partial extension support
 - add partial support for gpu_shader5 for textureGather*
 - add interactions between texture rectangle and textureGather*
 - add checks to distinguish between gpu_shader5 and texture_gather extension feature differences
