- Complete RetroFX filter (downscale+palette). - Additional palettes, extending to the full range of 64. - Localization support (just English for now). - Better slider input (shift for 10x increments, alt for 5x increments) - Use nosave cvars for performance and so they don't end up in savegames. - A lot of cleanup.
