Heat distortion shader (#42973)

* revert of the revert * tests * changes * more fun * test * ccvvvar * works but bad * now its better * more fixes * more cleanup * cleaning * last fixes before move to glasses activ * x * glasses only * working * fix toolbox * cleanup * ThermalByte added * small fix * small optimalisations * float bux fix * comments add * more comments * more comments * last fix * revert cvar delete * wrong blue shades * cvar refactor * Update Content.Shared/Atmos/EntitySystems/SharedGasTileOverlaySystem.cs Co-authored-by: ArtisticRoomba <145879011+ArtisticRoomba@users.noreply.github.com> * Update Content.Client/Atmos/Overlays/GasTileDangerousTemperatureOverlay.cs Co-authored-by: ArtisticRoomba <145879011+ArtisticRoomba@users.noreply.github.com> * tweak to TryGetTemperature comment * Factors are now const * renames * Interface for ThermalByte * tile color vaccum and more comments * saving yeeted * integration test * rename and cleanup * fix * cleanup * switch * UT fix (hopefully) * small bug+ rename * vaccum limit + space is now invalid * typo * typo * fix * init, works * move method around * renames and split * renames * heatblur * cleanup * more docs * resource cache * No dynamic perlin noise generation [no fun allowed] and new blur softening method * magic numbers and rename * misc cleanup * removed init values because display compat mode broken * misc cleanup --------- Co-authored-by: ArtisticRoomba <145879011+ArtisticRoomba@users.noreply.github.com>
