- 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
