Vulkan WSI wrapping

[tareksander]

• [ ] Generic Swapchain implementation
  • [ ] regular Vulkan memory buffers if HardwareBuffers aren't available
  • [ ] HardwareBuffer-backed VKImages if possible
• [ ] X11
  • [ ] Image flipping and color conversion
  • [ ] Like EGL, but this time we can't inject code in the shaders, so CPU formatting should be the default
  • [ ] It may be possible to run a separate graphics pipeline over the VKImages once they have been submitted to the Swapchain, to convert the format and flipping the X axis (or a compute pipeline could work even better for this workload)
  • [ ] Presenting also like EGL, via shared memory Pixmaps
• [ ] Wayland
  • [ ] More options for formats, choose one HardwareBuffers and the compositor support if possible
  • [ ] Doesn't need to flip the X axis
  • [ ] Try to create wl_shm buffers from HardwareBuffer DMABUF fd
  • [ ] Use the custom HardwareBuffer protocol if supported instead

Looks interesting, but only supports Wayland. Maybe I can add X11 support for it.
