Detailed Description

GrContext uses the following interface to make all calls into OpenGL. When a GrContext is created it is given a GrGLInterface. The interface's function pointers must be valid for the OpenGL context associated with the GrContext. On some platforms, such as Windows, function pointers for OpenGL extensions may vary between OpenGL contexts. So the caller must be careful to use a GrGLInterface initialized for the correct context. All functions that should be available based on the OpenGL's version and extension string must be non-NULL or GrContext creation will fail. This can be tested with the validate() method when the OpenGL context has been made current.
