More Vulkan Improvements Land In GTK4 Toolkit Code

A number of improvements have landed to the GTK4 tool-kit's early back-end work on supporting Vulkan as an alternative to its OpenGL renderer is gaining ground.

Some of the Vulkan GTK4 code that landed this past week include:

- Support for combining draw calls. This provides a 5~7% speedup, according to Red Hat developer Ben Otte.

- A shader for color drawing with rectangle clip.

- A proof of concept clip implementation.

- An implementation for gsk_renderer_render_texture().

- Pipeline changes.

- A GskVulkanUploader implementation, as said by the commit, "It's the thing that makes sure pixels end up on the GPU."

- Staging-buffer image upload support.

- Infrastructure work for supporting multiple pipelines.

- Various other changes and fixes.
