Benjamin Otte 2a0e7f8829 gsk: Loads of work on Vulkan backend
We can now upload vertices.

And we use this to draw a yellow background. Which is clearly superior
to not drawing anything.

Also, we have shaders now. If you modify them, you need glslc installed
so they can be recompiled into Spir-V bytecode.
