* Made spot size parameters adjustable also increased samples from 2 to 3 scanlines for crt-geom-deluxe.
* Made horizontal interpolation adjustable.
* bgfx crt-geom-deluxe: Made phosphor decay smoothly to zero at specified cutoff time.
* bgfx crt-geom-deluxe: Added lowpass filter.
Added a "brightness boost" feature for the shadow mask that works by making the brightness ratio between bright and dark mask pixels closer to 1 for the brighter parts of the image.
Added clamping to zero so that underscanning produces a black border.
Added a "raster bloom" effect to crt-geom-deluxe that makes the image grow slightly when the average brightness of the screen is high, mimicking a common defect in CRTs.
* Remove broken scanline uniform from post_pass
* Add 3D LUT to HLSL
* Allow individual LUTs for screen and UI
* WIP: Port 3D LUT to BGFX
* Finish porting LUT to BGFX
* Add individual phosphor color conversion for HLSL

Shader for converting xyY3 to sRGB

Minor changes to emphasize idea that phosphors are color
agnostic

* Fix missing newlines at EOF
This includes several aperture grille / shadow mask patterns. Note that these are all designed to be used on a display with RGB subpixel order, and may thus suffer if rotated or used with a BGR display.
- removed POT texture size from shadow mask in HLSL, U/V size is now simply the percentage of the actual texture size
- adjusted display names of options
- if specified all textures (.png) within the same directoy of the given texture will be selectable via slider in the UI
- also added slider for "shadow mask tile mode" to HLSL chain
