Adding more OpenGL-like functions for object manipulation
gpuTexCoordPointer = glTexCoordPointer
gpuClientActiveTexture = glClientActiveTexture

Now, in gl11 implementation, calling any gl*Pointer enables GL_*_ARRAY with glEnableClientState;
So, no need to call glEnableClientState
gpuCleanupAfterDraw must be called after glDraw* function to disable any enabled GL_*_ARRAY and reset internal state

In GLES functions gpuTexCoordPointer and gpuClientActiveTexture aren't yet implemented
