LibAccelGfx: Use wrapping functions with error check for OpenGL calls This change introduces GL.h with error check wrappers for all the OpenGL functions we used so far. For now, the error check is simply: `VERIFY(glGetError() == GL_NO_ERROR);` but that is better than continuing execution after encounting an error.
