- Added DisablePointLights slider to all materials
- Added HairPlusReflect
- Added HairFrontPlusReflect

- Added a slider to disable matcaps which fall in shadow
- Fixed MainOpaquePlusTess not working

Added:
- All shaders now support matcap shadowing
- Reflection coloring with 2 options sliders (ReflectCol, ReflectColAlphaOpt, ReflectColColorOpt)
- ReflectRotation slider: 0-360° matcap rotation
- ReflectMask for Skin/Hair reflect versions: black/white toggles between environmental and matcap reflections, defaults to white (matcap)
- ReflectMapDetail for item shaders: combination of ReflectMap (red channel) and ReflectMask (green channel)
 - Had to combine them due to technical limitations
- ShadowHSV: shadow color relative adjustment (for touchups)
- AdjustBackfaceNormals slider: Backfaces will be lit correctly but the item's reflection looks off (defaults to off, on would be the vanilla behavior)
- CullOption and Cutoff sliders for hair shaders
- All item shaders which didn't before now support AlphaMasks
- Alpha shaders now support smooth alpha (AlphaOptionCutoff = 2)
 - Gray AlphaMask values between `Cutoff` and 1 will be scaled to between 0 and 1
Fixes:
- Point lights now work correctly with matcap shadowing
- ReflectVal inconsistencies compared to 1.3.1 removed
- Matcap alphas now behave like in 1.3.1
- Front hair shaders now have the correct render queue (might mean needing to set "Show irises through hair" to Yes)

Add eye matcaps, fix eye Z rendering

Add more tess

Add Studio item plus

- fix eye matcaps extending beyond maintex
- fix absolute black problem with eye / eyetess
- fix transparency slider default
- fix transparency slider behaviour with outlines / reflections
- fix absolute black shadow color problem with studio shaders

## Additions:
- Exposed AlphaMask on Skin shaders
- Added ColMask / Col0 / Col1 / Col2 / Col3 to Skin shaders
## Fixes:
- Fixed all tiling issues ||hopefully||
- Eye emission now rotates with the eye
- Eye emission is no longer broken by too dark of a MainTex
- Fix hair reflections breaking things when parts of hair were hidden via MainTex
- Skin / Hair / Eye shaders' ReflectMap now functions correctly
- Skin / Hair / Eye shaders' ReflectMask can now be scaled/translated
- A bunch of StudioItem shader color nonsense
- StudioItem shaders now only speculate in the light
- StudioItem shaders are now properly lit with Point Lights (pointlight shadows still impossible)
- StudioItem shaders' speculars fixed all around
- StudioItem shaders' emission fixed

Fix DisableShadowedMatcap with cast shadows
