- Texture Matrix are 100% handled by gl4es. GLES Hardware keep an Identity matrix (TexCoord are transformed if needed). This allows a better handling of NPOT texture on hardware that doesn't support Full NPOT (fixed movies being horizontally shifted in openmw with LIBGL_NPOT=1 for example)
- Added gl4es specifics glHint capabilities. If the extension GL_GL4ES_hint is present, than a few Hint are accessible. Look in include/gl4eshint.h for the list.
- New name: gl4es
