New renderers for GTK

Recently, GTK gained not one, but two new renderers: one for GL and one for Vulkan.

Since naming is hard, we reused existing names and called them ngl" and vulkan". They are built from the same sources, therefore we also call them unified" renderers.

[...]

As mentioned already, the two renderers are built from the same source. It is modeled to follow Vulkan apis, with some abstractions to cover the differences between Vulkan and GL (more specifically, GL 3.3+ and GLES 3.0+). This lets us share much of the infrastructure for walking the scene graph, maintaining transforms and other state, caching textures and glyphs, and will make it easier to keep both renderers up-to-date and on-par.

This is well above my paygrade, but I'm sure it's still of interest to y'all.
