Benjamin Otte	73ac2d0a1c	gpu: Add a flip_y argument to shader execution ... Because GL flips its shit sometimes (ie when it's the framebuffer), pass the height of the target as the flip variable, so commands that need to operate on the pixels can flip the y axis around this value.	2024-01-07 07:22:49 +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
Benjamin Otte	9ddae8aebc	gpu: Add outline of new GPU renderer ... For now, it just renders using cairo, uploads the result to the GPU, blits it onto the framebuffer and then is happy. But it can do that using Vulkan and using GL (no idea which version). The most important thing still missing is shaders. It also has a bunch of copy/paste from the Vulkan renderer that isn't used yet. But I didn't want to rip it out and then try to copy it back later	2024-01-07 07:22:49 +01:00
