Christoph Oelckers	0461acfc8b	- removed the brightness fudging in the palette emulation shader and always return an alpha of 1. ... The fudging was only needed because fog was still applied on top of the palette emulation so after completely disabling the true color distance attenuation in palette mode it made the image too bright. The alpha needs to be 1 because this is only the texel, not the combined color.	2020-09-21 21:17:23 +02:00
Christoph Oelckers	29a10cabcb	- fixed most issues with palette emulation. ... Brightness is now correct - I have no idea why this factor of 1/0.85 is needed - something must reduce the brightness of the entire scene but I have no idea what.	2020-09-18 22:29:13 +02:00
