Adds colored and inverted colored variations for Luma Burn, enabling some more fancy transitions with it. All variations with color support smooth fading, and allow choosing any possible color for the transition.
* Fixed 'Pixelator's color transition point being off-center and uncontrollable.
* Fixed 'Drunk' filter not working at all.
* Added an inverted mode to 'Luma Burn'.
* Added exponential Luma to 'Luma Burn'.
* Fixed odd color behavior in the 'Color Shift' transition by switching out HSL with HSV.
* Added a new 'Sliding Bars' transition shader, for an example of it see this clip: https://clips.twitch.tv/RacyEndearingHorseradishAMPTropPunch .
Color Shift: Uses HSL and some math to smoothly shift Hue Saturation and Lightness between A and B.
Luma Burn: "Burns" away the Luminosity of A to reveal the B side.
Pixelator: Classic/Retro pixelation effect often seen in older games to transition between settings.
