examples: Fix some example shaders and add new ones
* 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 .
