1733671295 gpu: Add a CommandState struct to the command vfuncs
This way, we can make it writable and track things like the active
textures and the current program.

We don't do that yet, but we can.

73ac2d0a1c gpu: Add a flip_y argument to shader execution
Because GL flips its shit sometimes (ie when it's the framebuffer),
pass the height of the target as the flip variable, so commands
that need to operate on the pixels can flip the y axis around this value.

1a85d569e3 gpu: Add ability to run shaders
This heaves over an inital chunk of code from the Vulkan renderer to
execute shaders.

The only shader that exists for now is a shader that draws a single
texture.
We use that to replace the blit op we were doing before.

9ddae8aebc gpu: Add outline of new GPU renderer
For now, it just renders using cairo, uploads the result to the GPU,
blits it onto the framebuffer and then is happy.

But it can do that using Vulkan and using GL (no idea which version).

The most important thing still missing is shaders.

It also has a bunch of copy/paste from the Vulkan renderer that isn't
used yet.
But I didn't want to rip it out and then try to copy it back later
