bd18250672 Revert "- prevent excessively bright pixels as this is actually visible on a HDR monitor"
This reverts commit 56d788f237181e04354042de4596135fd2fda193.

It caused graphics glitches with the partial invisibility effect.

3ed0541647 Revert "- Fixed dithering in the present shader."
This reverts commit b359b65f35.

It gave a shader compile error on hardware not supporting GL 4.2.

98607f594e - use the exact sRGB->linear transfer function in HDR mode as the 2.2 gamma approximation is visibly inaccurate in this case

c2a3895bfe Revert "- add dithering to present shader"
This reverts commit 60ae0915b9.

This was extremely slow on intel, the dither matrix was recreated on every frame even when not used.

b4915d624d - removed 'cooling' component of the shader since it technically wasn't really functional (guess we have to use a separate shader to do that)
- changed the math to use the 'mix' formula

bd02893ce7 - expanded hard limits for saturation to -15.0/15.0
- added menu option for saturation
- tried to get the new saturation shader to consume less GPU power by turning it off when it is 1.0

63da6e70c0 - added a vid_saturation control - works in postprocessing, only. 2017-07-02 16:45:06 -04:00

72491049e0 Changes to the contrast/brightness/gamma formula for both hardware and shader gamma correction. Mainly makes a correction with the shader version where contrast/brightness being negative values would clip them inappropriately. 2016-09-22 09:23:25 +02:00

a8d1197ea7 Make sure we never pass a negative value to pow, and optimize gamma uniform 2016-08-16 00:01:18 +02:00
