- Add support for pointer-gestures-unstable-v1.
- Configs can now handle switch events (laptop lid closed/opened).
- Add support for tablet-v2.
- Add support for linear framebuffers (hardware cursors/screensharing) on NVIDIA if the Vulkan renderer is used. (The OpenGL renderer does not support this.)
