Pictureflow optimisations: (1) No need to restore the drawmode, the core takes care of that. (2) Making the angle positive before masking is redundant. (3) Slide rendering: * Precalculate a faded reflection table for alpha < 256, saving a multiply in the inner loop. * Group the inner loops so that less variables are precalculated, helping to keep stuff in registers. * Combine loop conditions so that a single check is sufficient.
