8f56d03d4b
A Vulkan renderer for weston, based on the GL renderer. The goal is to impose the least requirements as possible on Vulkan implementations, as to allow even Vulkan 1.0 (or early development) drivers to run a Wayland compositor. Any additional features or extensions are made optional if possible. Currently supports drm, wayland, x11 and headless backends. As of this implementation, this is still considered an experimental renderer. Signed-off-by: Erico Nunes <nunes.erico@gmail.com>
