Benjamin Otte	177b19a2da	gpu: Use variations in the straight-alpha shader ... This way we can toggle opacity handling on/off. THe shader slowly turns into a fancy texture op - but I don't want to rename it to "fancytexture" just yet.	2024-01-07 07:22:53 +01:00
Benjamin Otte	9947760d87	gpu: Handle alpha in image_op() wrapper ... There are various places where the alpha is implicitly assumed to be handled, so just handle it. As a bonus, this simplifies a bunch of code and makes the texture node rendering work with alpha.	2024-01-07 07:22:53 +01:00
Benjamin Otte	b4a1ed2a70	gpu: Add straight alpha support ... Add a GSK_GPU_IMAGE_STRAIGHT_ALPHA and use it for images that have straight alpha. Make sure those images get passed through a premultiplying pass with the new straight alpha shader. Also remove the old Postprocess flags from the Vulkan image that were a leftover from copying that code from the old Vulkan renderer.	2024-01-07 07:22:51 +01:00
