Start work on a Vulkan-based renderer Doesn't do much other than create an instance and enumerate some stuff, but the build system is working.

vulkan vid stuff from the renderer.
[vulkan] Correct a pile of copyright attributions Id Software had pretty much nothing to do with the vulkan renderer (they still get credit for code that's heavily based on the original quake code, of course).

Completely rework the vulkan related api Things don't work yet, but this feels much cleaner.

[vulkan] Start moving towards a deferred renderer After getting lights even vaguely working for alias models, I realized that it just wasn't going to be feasible to do nice lighting with forward rendering. This gets the bulk of the work done for deferred rendering, but still need to sort out the shaders before any real testing can be done.

[vulkan] Use correct vertex shader for skys This gets skys rendering again, but their depth is incorrect.

QFV_passDepth, // geometry
[vulkan] Fix sky depth issues There were actually several problems: translucency wasn't using or depending on the depth buffer, and the depth buffer wasn't marked as read-only in the g-buffer pass. Getting that correct seems to have given bigass1 a 0.5% boost (hard to say, could be the usual noise).

QFV_passGBuffer, // geometry
[vulkan] Switch to full screen triangle instead of quad While I have trouble imagining it making that much performance difference going from 4 verts to 3 for a whopping 2 polygons, or even from 2 triangles to 1 for each poly, using only indices for the vertices does remove a lot of code, and better yet, some memory and buffer allocations... always a good thing. That said, I guess freeing up a GPU thread for something else could make a difference.

[vulkan] Add a position buffer to the g-buffer While I could reconstruct the position from the screen coords and depth, this is easier and good enough for now. Reconstruction is an optimization thing.

[vulkan] Implement deferred emission (fullbrights) That was... easier than expected. A little more tedious that I would have liked, but my scripting system isn't perfect (I suspect it's best suited as the output of a code generator), and the C side could do with a little more automation.

Remove global vulkan_ctx While I can't say that I'm happy with the details of vulkan_ctx_t, I am pretty sure I don't want to be limited to having only one.

[vulkan] Support multiple render passes Multiple render passes are needed for supporting shadow mapping, and this is a huge step towards breaking the Vulkan render free of Quake, and hopefully will lead the way for breaking the GL renderers free as well.

[vulkan] Add support for compute shaders This needed changing Vulkan_CreatePipeline to Vulkan_CreateGraphicsPipeline for consistency (and parsing the difference from a plist seemed... not worth thinking about).

[vulkan] Rework pipeline parsing for better reuse It's not entirely there yet, but the basics are working. Work is still needed for avoiding duplication of objects (different threads will have different contexts and thus different tables, so necessary per-thread duplication should not become a problem) and general access to arbitrary fields (mostly just parsing the strings)

[vulkan] Add entity labels to command queues Brush models looked a little too tricky due to the very different style of command queue, so that's left for now, but alias, iqm and sprite entities are now labeled. The labels are made up of the lower 5 hex digits of the entity address, the position, and colored by the normalized position vector. Not sure that's the best choice as it does mean the color changes as the entity moves, and can be quite subtle between nearby entities, but it still helps identify the entities in the command buffer. And, as I suspected, I've got multiple draw calls for the one ogre. Now to find out why.
