CC_Time[n] seems to always stay at 0 when a Shader uses CC_MVPMatrix.
With CC_PMatrix it works fine, but using CC_PMatrix for labels will trigger OpenGL error 0x0502 in CCTextureAtlas.
Is there any other way to get a timer? Or is there anything to solve the OpenGL error? The shader seems to work even with the error message repeating endlessly in the log, but ignoring it is probably not a good idea?
