efc3443c61 [vulkan] Create a water warp output pipeline
Although it works as intended (tested via hacking), it's not hooked up
as the current frame buffer handling in r_screen is not readily
compatible with how vulkan output is handled. This will need some
thought to get working.

2cee2f2ab8 [vulkan] Add a module to handle output
When working, this will handle the output to the swap-chain images and
any final post-processing effects (gamma correction, screen scaling,
etc). However, currently the screen is just black because the image
for getting the main render pass output isn't hooked up yet.

82d1a6e6cd [vulkan] Do a depth pass for 2d objects
While the HUD and status bar don't cut out a lot of screen (normally),
they might start to make a difference when I get transparency working
properly. The main thing is this is a step towards pulling the 2d
rendering into another render pass so the main deferred pass is
world-only.

2828a4ce0c [vulkan] Use a swizzle view for coverage-alpha
And thus a single pipeline for either colored glyphs or coverage-alpha
glyphs, making for better batching when I get to that.

bffe9413b7 [vulkan] Add support for 9-slice rendering
There's no API yet as I need to look into the handling of qpic_t before
I can get any of this into the other renderers (or even vulkan, for that
matter).

However, the current design for slice rendering is based on glyphs (ie,
using instances and vertex pulling), with 3 strips of 3 quads, 16 verts,
and 26 indices (2 reset). Hacky testing seems to work, but real tests
need the API.

f477f2b96e [vullkan] Rework Draw implementation
Line rendering now has its own pipeline (removing the texture issue).

Glyph rendering (for fonts) has been reworked to use instanced quad
rendering, with the geometry (position and texture coords) in a static
buffer (uniform texture buffer), and each instance has a glyph index,
color, and 2d base position.

Multiple fonts can be loaded, but aren't used yet: still just the one
(work needs to be done on the queues to support multiple
textures/fonts).

Quads haven't changed much, but buffer creation and destruction has been
cleaned up to use the resource functions.

e5932d1f92 [vulkan] Support Vulkan's pNext in vkparse/vkgen
The real reason for the delay in implementing support for pNext is I
didn't know how to approach it at the time, but with the experience I've
gained using and modifying vkparse, the solution turned out to be fairly
simple. This allows for the use of various extensions (eg, multiview,
which was used for testing, though none of the hookup is in this
commit). No checking is done on the struct type being valid other than
it must be of a chainable type (ie, have its own pNext).

cd66dbfc97 [vulkan] Implement font rendering
It is currently an ugly hack for dealing with the separate quad queue,
and the pipeline handling code needs a lot of cleanup, but it works
quite well, though I do plan on moving to HarfBuzz for text shaping. One
nice development is I got updating of descriptor sets working (just need
to ensure the set is no longer in use by the command queue, which the
multiple frames in flight makes easy).

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.

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.

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).

36e0d857a2 [vulkan] Create the non-C side of the sprite pipeline
This adds the shaders and the pipeline specs. I'm not sure that the
deferred rendering side of the render pass is appropriate, but I thought
I'd give it a go, since quake sprites are really cutoff rather than
translucent.

8c03ed8be5 [vulkan] Start work on shadows
This gets the shaders needed for creating shadow maps, and the changes
to the lighting pipeline for binding the shadow maps, but no generation
or reading is done yet. It feels like parts of various systems are
getting a little big for their britches and I need to do an audit of
various things.

5f93c115ff [util] Make developer flag names easier to manage
They're now an enum, and the flag part of the name is all lowercase, but
now the flag definitions and names list will never get out of sync.

7e946a4de9 [vulkan] Implement water surface rendering
They're unlit (fullbright, but that's nothing new for quake), but
working nicely. As a bonus, sort out the sky pass (forced to due to the
way command buffers are used).

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.

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.

resources. It is already used for shaders, set layouts, and pipeline
layouts.

e4f75791ce [vulkan] Clean up some tangled dependencies
Dependencies on vkparse.hinc were spreading through the code which I
didn't want as that removes a lot of the automation from the automake
files. This keeps all parser code internal to vkparse.c's scope, and any
accesses required for enum and struct (not yet) definitions can be
fetched by name.

7fb335a215 [vulkan] Add support for building and loading shaders
Shaders can be built as spv files and installed into
$libdir/quakeforge/shaders or as spvc files and compiled into the
engine. Loading supports $builtin/name to access builtin shaders,
$shader/path to access external standard shaders and quake filesystem
access for all other paths.
