7901f87960 [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).

d5b824a47c [vulkan] Switch alias pipeline to multi-texture
This gets the alias pipeline in line with the bsp pipeline, and thus
everything is about as functional as it was before the rework (minus
dealing with large texture sets).

8422732505 [vulkan] Move matrices into per-frame buffers
This should fix the horrid frame rate dependent behavior of the view
model.

They are also in their own descriptor set so they can be easily shared
between pipelines. This has been verified to work for Draw.

928408bad9 [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.

56c2fa380b [vulkan] Implement view model rendering
Quake just looked wrong without the view model. I can't say I like the
way the depth range is hacked, but it was necessary because the view
model needs to be processed along with the rest of the alias models
(didn't feel like adding more command buffers, which I imagine would be
expensive with the pipeline switching).

f1ac8f2460 [renderer] Remove currententity from non-sw renderers
Really needed only for vulkan, but removing currententity from gl and
glsl made testing easier.

e50a079f72 [vulkan] Fix some 32-bit compatibility issues
mostly dealing with vulkan's handles always being 64-bit, but pointers
being either 32 or 64.

f13af65b32 [vulkan] Move viewport and scissor into vulkan_ctx
Not only does it makes sense to centralize the setting of viewport and
scissor, but it's actually necessary in order to fix the upside-down
rendering on windows.

6e0312658d [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).

fbc1bd9f6e [renderer] Clean up entity_t to a certain extent
This is the first step towards component-based entities.

There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.

As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.

10a1b99a92 [vulkan] Implement lighting and compose passes
Lighting doesn't actually do lights yet, but it's producing pixels.
Translucent seems to be working (2d draw uses it), and compose seems to
be working.

e6ecf5e855 [vulkan] Fix up commands for deferred rendering
Nothing gets output yet (lighting and composite passes not implemented),
but everything passes validation until exit (not destroying everything).

cbc8ad271a [vulkan] Convert bsp and draw to deferred

a94949c009 [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.

1275067655 [vulkan] Rename vulkan_framebuffer_t
It turns out I had conflated frame buffers with frames and wound up
making a minor mess when separating the number of frames the renderer
could have in flight from the number of swap-chain images. This is the
first step towards correcting that mistake.

8179c44042 [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)

d6b678ac78 [vulkan] Implement team colors
It's not quite as expected, but that may be due to one of msaa, the 0-15
range in the palette not being all the way to white, the color gradients
being not quite linear (haven't checked yet) or some combination of the
above. However, it's that what should be yellow is more green. At least
the zombies are no longer white and the ogres don't look like they're
wearing skeleton suits.

8e63ab9f94 [vulkan] Use 4 layer arrays for alias skins
Doesn't seem to make much difference performance-wise, but speed does
seem to be fill-rate limited due to the 8x msaa. Still, it does mean
fewer bindings to worry about.

34dc7cf2df [models] Move brush data into its own struct
This is a big step towards a cleaner api. The struct reference in
model_t really should be a pointer, but bsp submodel(?) loading messed
that up, though that's just a matter of taking more care in the loading
code. It seems sensible to make that a separate step.

eeda04e3c9 [vulkan] Name most resources
This makes debugging with renderdoc and validation messages much easier
(no more "what buffer is that?").

7ee02f3965 [vulkan] Sort of implement ambient lighting
It works, but as it uses the camera position rather than the lit
entity's position, it is incorrect. I have some interim ideas to handle
it, though.

206c631811 [vulkan] Get alias lighting mostly working
It's not so much that parts aren't working, but rather there's no
base-level lighting so everything is black until a dlight is in the
vicinity

28652c4d59 [vulkan] Implement alias model texturing
I had messed up my index array creation, but once that was fixed the
textures worked well other than a lot of pixels are shades of grey due
to being in the top or bottom color map range.

64904e2b27 [vulkan] Switch over to pushed descriptors
I don't really know why (I need to do some research), but this fixes the
lockups when accessing the matrices UBO. It has made a mess of my
carefully designed uniform binding layout, so I hope I can get bound
descriptor sets working the way I want, but I really need to progress on
the rest of the project.

buffer.

9f64416846 [vulkan] Create the lights buffer
It's a tad bogus as it's the lights close to the camera, but it should
at least be a good start once things are working. There's currently
something very wrong with the state of things.
