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.

2c5742a076 [renderer] Remove some variable warts
Ugh, Hungarian notation is still lurking...

0366b72d4a [vulkan] remove the fps printing
Now that pixels are rendered, there's no need to print the fps
separately as the in-game display works quite nicely.

4d8ce22c17 [vulkan] Load the map's lights into an array
It's not used yet as work needs to be done to better support generic
entities, but this is the next step to real-time lighting (though, to be
honest, I expect it will be too slow to be usable).

eb0aa2dcea [renderer] Clean up most globals in efrags
There's still the memory management itself to clean up, but the main
code no longer uses any static/global variables (holdover from when the
function was recursive rather).

9617bbef97 [build] Create static libs for render targets
The static libs are used to build the plugins, but make it easy to use
only those modules needed for tests. Fixes the link error when running
"make check" with non-static plugins.

fd97bb1456 [vulkan] Implement linear falloff
It's possibly too bright, but it might be the lights themselves. Still,
it looks better than the no-falloff implementation.

33575f93d5 [vulkan] Implement deferred lighting for dlights
Static lights are yet to come (so the screen is black most of the time),
but dynamic lights work very nicely (and look very good) despite the
falloff being incorrect.

918c3af095 [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.

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).

4245c6ad3b [vulkan] Specify subpass number in pipeline def
This gets the alias model render pass and pipeline passing validation.

I don't know why I didn't add the subpass field to the
VkGraphicsPipelineCreateInfo parser def, though it could be I simply
missed it, or I thought I wouldn't need it at the time.

64740b0f73 [vulkan] Create shaders for alias deferred rendering
A simple (no uv output) vertex shader that still blends the two frames,
and the relevant g-buffer fragment shader.

b08c3881b9 [vulkan] Add a comment about using size_t
Due to wanting to access array sizes when parsing uint32_t type values,
parse_uint32_t needs to handle size_t values even though it throws out
any excess bits.

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.

f023675f8c [vulkan] Clean up draw's memory handling a little
Use cmem for pic and cachpic name allocations. If nothing else, it at
least keeps memory a little less fragmented.

c536a363ec [vulkan] Remove namehack.h
Never really wanted in the first place (back when I did the plugin
renderers), but I didn't feel like doing the required work to avoid it
at the time. At least with Vulkan being a fresh start in an environment
that's already plugin-friendly, there was no real work involved. I'll
get to the other renderers eventually (especially now that I know gdb
does the right thing when there are multiple functions with the same
name).

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.

e929dca300 [util] Auto-cast plist string items
The casting uses a recursive call to the expression parser, so the
expressions are type-checked automatically.

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)

bc7858bb87 [model] Move parent pointer out of leaf/node struct
The node struct was 72 bytes thus two cache line. Moving the pointer
into the brush model data block allows nodes to fit in a single cache
line (not that they're aligned yet, but that's next). It doesn't seem to
have made any difference to performance (at least in the vulkan
renderer), but it hasn't hurt, either, as the only place that needed the
parent pointer was R_MarkLeaves.

ebb73e19b2 [vulkan] Use the msaaSamples cvar
That took a bit of fiddling with the render pass to get things working
for both sampling and no sampling (ie, msaaSamples = 1).

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.

afe8e9633e [vulkan] Silence the matrix dump

c7eafd9254 [vulkan] Make the mip map generation public
I've decided that alias model skins should be in a single four-level
array texture rather than spread over four textures, but there's no way
I want to write that code again: getting it right was hard enough the
first time :P

eeda04e3c9 [vulkan] Name most resources

7970525ef4 [util] Make va thread-safe
It now takes a context pointer (opaque data) that holds the buffers it
uses for the temporary strings. If the context pointer is null, a static
context is used (making those uses of va NOT thread-safe). Most calls to
va use the static context, but all such calls have been formatted
consistently so they are easy to find when it comes time to do a full
audit.

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.

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.
