This change implements a Vulkan port for the two renderers, old and compute. Run with GIORENDERER=forcecompute to test the compute renderer. To shake out bugs faster, it is also made the default on systems that support it. To disable Vulkan and force the use of OpenGL, use the `novulkan` tag: $ go run -tags novulkan gioui.org/example/kitchen Don't forget to file an issue describing the issue that prompted the use of the tag.
