Benjamin Otte	74ac95dc32	gpu: Don't try to be smart ... Don't try to use all those fancy GL features like glMapBuffer() and such. Just malloc() some buffer memory and glBufferSubData() it later. That works everywhere and is faster than (almost?) any combination of fancy new buffer APIs. And yes I'm frustrated because I played with those flags and none of them were better than this. Doubles the framerate on my discrete AMD GPU.	2024-01-07 07:22:50 +01:00
Benjamin Otte	c6e19f0384	gpu: Add float array to shaders and add an ubershader ... ... and use it for a naive color node implementation using both so I can test it actually works.	2024-01-07 07:22:50 +01:00
Benjamin Otte	1a85d569e3	gpu: Add ability to run shaders ... This heaves over an inital chunk of code from the Vulkan renderer to execute shaders. The only shader that exists for now is a shader that draws a single texture. We use that to replace the blit op we were doing before.	2024-01-07 07:22:49 +01:00
