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 2023-08-12 20:10:16 +00:00			`#pragma once`

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. 2023-08-21 00:18:37 +00:00			`void gsk_gl_frame_use_program (GskGLFrame *self,`

gpu: Introduce the concept of "variation" A variation is a #define/specialization constant that every shader can use to specialize itself as it sees fit. This commit adds the infrastrcture, future commits will add implementations. 2023-12-31 04:38:56 +00:00			`guint32 variation,`
gpu: Prepare GL rendering for samplerExternalEOS Carry an n_external_textures variable around when selecting programs and compile different programs for different amounts of external textures. For now, this code is unused, but dmabufs will need it. 2023-11-02 01:53:50 +00:00			`GskGpuShaderClip clip,`

gpu: Handle storage buffers via descriptors This makes the (currently single) storage buffer handled by GskGpuDescriptors. A side effect is that we now have support for multiple buffers in place. We just have to use it. Mixed into this commit is a complete rework of the pattern writer. Instead of writing straight into the buffer (complete with repeatedly backtracking when we have to do offscreens), write into a temporary buffer and copy into the storage buffer on committing. 2023-11-19 14:27:10 +00:00			`void gsk_gl_frame_bind_globals (GskGLFrame *self);`
