Christoph Oelckers	4937848123	- refactoring of fixed colormap stuff to have it better organized and to reduce the number of uniforms in the main shader. ... This removes 3 uniforms, consisting of 9 floats. Those were merged into other values that never get used at the same time. It also moves the costly setup of the fixed colormap out of the render state into the 2D processing code. Since 3D forces use of render buffers now, it is no longer necessary to draw the entire scene with the colormap active, meaning it can be handled more efficiently.	2018-06-16 22:40:44 +02:00
Christoph Oelckers	8ab68264c1	- removal of all code to handle OpenGL 2. From this commit on the main build of GZDoom will be OpenGL 3.3 or higher. ... # Conflicts: # src/gl/renderer/gl_renderer.cpp # src/gl/shaders/gl_shader.cpp # src/gl/system/gl_framebuffer.cpp # src/gl_load/gl_interface.cpp	2018-06-15 21:45:05 +02:00
Christoph Oelckers	612fb40f3a	- don't use uniforms related to fixed colormaps for other things. ... The fixed colormap is a per-scene global setting that normally does not need to change ever during rendering of a scene so it's easily shoved aside into a static uniform buffer. Having to change this buffer for inconsequential stuff should be avoided, especially when there's other uniforms that are just as good to hold these values.	2018-06-14 21:28:03 +02:00
Christoph Oelckers	401c9ab8ca	- moved gl_interface.cpp/h to gl_load folder. ... These files are not part of the actual renderer but part of the system code. This means, for separated modern and legacy GL renderers, there still will only be one set of this, unlike everything else.	2018-05-16 23:21:21 +02:00
