- COpenGLTexture::getOpenGLFormatAndParametersFromColorFormat now returning values for ECF_R5G6B5 which can be used in glTexImage2D. Fixes test renderTargetTexture. I've also added a few more error-checks in debug.
- Remove assert in opengl driver (already logs and asserts prevent tests from running through).
- NOTE: 2 new tests failing: b3dAnimation and md2Animation. Maybe due to animation fix from yesterday.
