Cleaned up the bloom code a little, fixed bloom so view2/splitscreen doesn't cause the main view to get a double dose, by pulling the pixel offsets from outside rather than recalculating them (thus no longer wrongly assuming a full screen). Made the code slightly more readable - no more ugly braces!
