Benjamin Otte	ae3efb2d2f	gpu: Implement transform support for dihedral transforms ... This allows handling them without ever needing to offscreen for losing the clip, because the clip can always be transformed. Also, all the optimizations keep working, like occlusion culling, clears, and so on. The main benefit of this work is the ability for offloading to now handle dihedral transforms of the video buffer. The other big advantage is that we can now start our rendering with a dihedral transform from the compositor.	2024-07-10 21:34:12 +02:00
Benjamin Otte	208b2d37b6	gpu: Clarify clip types ... CLIP_TYPE_NONE is valid if the clip is implemented by the scissor rect. We always have a scissor rect and there's no way to draw outside of it. In theory that means we can reset the clip to NONE at any point we wish if we know nodes are contained inside a certain pixel-aligned rectangle we can clip. In practice that's probably quite hard...	2024-03-11 01:39:40 +01:00
Benjamin Otte	a51c6aed47	gpu: Introduce "contained" clip ... This clip is different from "none" in that the bounds rect cannot be ignored and that potential drawing outside the clip must be avoided. In particular it means that clip nodes cannot be discarded if they encompass the full clip region. Fixes #6322	2024-01-12 20:06:04 +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
