In GL, the default viewport and scissor should be set to the size of the first surface that the context is bound to. If a CoglGLES2Context is first used with an offscreen framebuffer then this surface will actually be the dummy 1x1 window which will mess up the defaults. To fix that, this patch makes it just always override the viewport and scissor the first time the context is bound to something.
