Benjamin Otte	b7a8c2207e	gpu: Introduce gsk_texture() shader function/macro ... Due to GLES and old GL not allowing non-constant texture array lookups,we need to turn the array lookup into a big switch statementin those versions, and that requires putting the texture() call into that switch. But with that trick, we can use texture IDs in GLSL.	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
