increase the granularity of the brightness vs clarity parameter to accommodate faster refresh rates and add a slew multiplier to make the LCD anti-retention bar less distracting by making it move faster
* fix on d3d and add parameter to move raster
* more direct fix for d3d compilers
instead of unrolling the loop, just stop using the loop iterator as the swizzle. This will allow us to keep the code more readable and closer to upstream.
* big reorganization of handheld and presets
* replace edge-blended-240hz-bfi with blurbusters and lottes' crt-beam-simulator
* whoops, forgot to track the new shader
