a08261c620 [vulkan] Use a buffer for entity transform and color data
This allows the use of an entity id to index into the entity data and
fetch the transform and colormod data in the vertex shader, thus making
instanced rendering possible. Non-world brush entities are still not
rendered, but the world entity is using both the entity data buffer and
entid buffer.

978d0306c0 [hash] Rename the publicly visible hashlink_t to hashctx_t
I think my biggest problem with the hashlink freelist parameter was how
much implementation it exposed in just the name.

bbca22c722 [vulkan] Add support for IQM models
Despite the base IQM specification not supporting blend-shapes, I think
IQM will become the basis for QF's generic model representation (at
least for the more advanced renderers). After my experience with .mu
models (KSP) and unity mesh objects (both normal and skinned), and
reviewing the IQM spec, it looks like with the addition of support for
blend-shapes, IQM is actually pretty good.

This is just the preliminary work to get standard IQM models loading in
vulkan (seems to work, along with unloading), and they very basics into
the renderer (most likely not working: not tested yet). The rest of the
renderer seems to be unaffected, though, which is good.

12c84046f3 [cvar] Make cvars properly typed
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.

As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.

The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).

While not used yet (partly due to working out the design), cvars can
have a validation function.

Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.

nq-x11 is known to work at least well enough for the demos. More testing
will come.

b2d4fa0ccf [vulkan] Break render pass parsing away from swapchain
This allows a single render pass description to be used for both
on-screen and off-screen targets. While Vulkan does allow a VkRenderPass
to be used with any compatible frame buffer, and vkparse caches a
VkRenderPass created from the same description, this allows the same
description to be used for a compatible off-screen target without any
dependence on the swapchain. However, there is a problem in the caching
when it comes to targeting outputs with different formats.

9892e571ce [vulkan] Move viewport and scissor into qfv_renderpass_t
This makes much more sense as they are intimately tied to the frame
buffer on which a render pass is working. Now, just the window width
and height are stored in vulkan_ctx_t. As a side benefit,
QFV_CreateSwapchain no long references viddef (now just palette and
conview in vulkan_draw.c to go).

11e30583cf [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.

acffacc59b [renderer] Make screen capture support asynchronous operation
This fixes (*ahem*) the vulkan renderer segfaulting when attempting to
take a screenshot. However, the image is upside down. Also, remote
snapshots and demo capture are broken for the moment.

db6c76d583 [vulkan] Abandon bindless rendering
At least for now, it is more trouble than it is worth as it (or my
implementation of it) breaks lavapipe and renderdoc.

6aaf5c3722 [vulkan] Start work on particles for Vulkan
This gets the pipelines loaded (and unloaded on shutdown). Probably the
easy part :P. Still need to sort out the command buffers,
synchronization, and particle generation (and probably a bunch else
that's not coming to mind).

c366b1b7bb [vulkan] Implement the sprite render passes
It turned out the bindless approach wouldn't work too well for my design
of the sprite objects, but I don't think that's a big issue at this
stage (and it seems bindless is causing problems for brush/alias
rendering via renderdoc and on my versa pro). However, I have figured
out how to make effective use of descriptor sets (finally :P).

The actual normal still needs checking, but the sprites are currently
unlit so not an issue at this stage.

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.

8b85e422d7 [vulkan] Add a debug stack to the vulkan instance
The stack is arbitrary strings that the validation layer debug callback
prints in reverse order after each message. This makes it easy to work
out what nodes in a pipeline/render pass plist are causing validation
errors. Still have to narrow down the actual line, but the messages seem
to help with that.
Putting qfvPushDebug/qfvPopDebug around other calls to vulkan should
help out a lot, tool.
As a bonus, the stack is printed before debug_breakpoint is called, so
it's immediately visible in gdb.

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

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)

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.

5186d3ae49 [vulkan] Rework draw to use a context struct
Cleans up global space and makes it usable in multiple contexts. Also,
max quads dropped to 32k as each frame now has its own vertex buffer to
avoid issues with vertex overwrites (which I have seen). However, all
vertex buffers are in the one memory/buffer object (using offsets) and
the index buffer has been moved into a device-local memory object.

904a91c0b7 [vulkan] Use only one global staging buffer
I think I did two as a bit of a ring buffer, but the new ring buffer
system used inside a staging buffer makes it less necessary. Also, the
staging buffer is now a fair bit bigger (4M is probably not really
enough)

bb4ca7683e [vulkan] Get the 2D pipeline up and running
First pixels! This was a nightmare of little issues that the validation
layers couldn't help with: incorrect input assembly, incorrect vertex
attribute specs. Though the layers did help with getting the queues
working. Still, lots of work to go but this is a major breakthrough as
I now have access to visual debugging for textures and the like.

ba6450d0b4 [vulkan] Make a start on the 2D pipeline
Short wrappers for Draw functins are in vid_render_vulkan.c so the
vulkan context can be passed on to the actual functions. The 2D shaders
are set up similar to those in glsl, but with full 32-bit color (rgba)
support instead of paletted. However, the textures are not loaded yet,
nor is anything bound.
