Dennis-Z	634ee96f54	Implement OpenGL renderer FilterRect through palette remapping ... Replace the previous "filtering" of rectangles based on luminance, now using a remap palette like the software renderer for better output colors. Various other simplifications regarding to rectangle rendering are included here too.	2017-08-16 00:43:41 +02:00
William Wallace	fbb424ba21	Add enums for DrawImageInstance flags	2017-07-13 18:10:14 +01:00

duncanspumpkin	5f7a6fb369	Fixed OpenGL palette drawing ... Added palettes to the texture atlas and now correctly use them to generate images. Transparency semi supported but the colours are not quite correct.	2016-09-18 20:28:46 +01:00
