update crt-geom-deluxe to add brightness compensation; add bright pix… (#170)

* update crt-geom-deluxe to add brightness compensation; add bright pixel counts to subpixel masks; delete extraneous preset

* forgot to update geom-deluxe preset

* fix various preset spec nits

* try to mellow out the raster bloom

-Guest-dr-venom-maxDR
-
-A PVM/BVM-style preset for guest-dr-venom created with the goal of maximizing the dynamic range of the image. 
-
-For best results, increase your LCD backlight to 100%. Color settings may need to be adjusted per-system or per-game; see the shader notes within grade.slang for suggestions. Color temp may also need to be adjusted depending on the color temp of your display. 
-
-Preset created by Nesguy at Libretro forums (https://forums.libretro.com/). Feedback and suggestions are welcome :)

 Multiply your image by the vec3 output:
 FragColor.rgb *= mask_weights(gl_FragCoord.xy, 1.0, 1);
 
+In the vec3 version, the alpha channel stores the number of lit subpixels per pixel for use in brightness-loss compensation efforts.

 The function needs to be tiled across the screen using the physical pixels, e.g.
 gl_FragCoord (the "vec2 coord" input). In the case of slang shaders, we use
 (vTexCoord.st * OutputSize.xy).
