Title: Fixed unscaled scissor rectangle on iOS

On iOS, there was an unscaled scissor rectangle applied in CreateFramebuffer(). If ScissorTest is enabled and the screen is rotated on a retina device (where scale is 2), a smaller scissor rectangle is applied that's half the size of the screen on retina devices, resulting in only the lower left quarter of screen being used for drawing.

This problem was well hidden, as lots of thing reapply a correct scissor rectangle (for example rendertargets).
