- r_leifx cvar that controls the magnitude of faking a certain ubiquitous video card, requires leifx_filter/dither/gamma shaders (not committed yet)

- r_slowness, r_slowness_cpu and r_slowness_gpu cvars that sort of fake system bottlenecks. not useful for playing
- more r_modes, no standards followed.
- some additional but dummied out model shading functions
