Fix for setContinuousRendering(false) in iOS backend
Update IOSInput
Small bugfix which ensures that the Color variable in PolygonSprite is set all over, instead of querying the vertex colors. (Which can differ from the actual set color due to packing).
Also fixes bug where current color isn't used to set vertex color when setRegion is used. (As color wasn't being maintained)
