Refactoring
- replaced shader parameters OrientationSwapXY xor RotationSwapXY by
SwapXY
- made shader parameters SourceDims, SourceRect, TargetDims, ScreenDims,
QuadDims and SwapXY available for all shaders
- color convolution, defocus and phosphor pass will now be skipped if
all influencing parameters are 0
- removed unused bloom_texture and bloom_target arrays from cache_target
class
- fixed half texel offset in prescale.fx
