40fc9f0000 [model] Make Mod_LoadExternalTextures private 
It never really needed to be externally accessible as it has always been
gl-specific and can be called by Mod_ProcessTexture anyway.

dacda50130 [renderer] Stub out all the vulkan functions 
nq-x11 now gets through all three demos without crashing (but without
rendering anything useful, though).

8078e10ea1 [vulkan] Make frame-buffers independent of swapchain 
This is more correct as the environment (X11 etc) might provide more
swapchain images than we want: 3 frames in flight is generally
considered a good balance between saturating the hardware and latency.

ad9c3193fa [vulkan] Use darray size to control cmd buffer count 
This allows the array in which the command buffers are allocated to be
allocated on the stack using alloca and thus remove the need to
malloc/free of relatively small chunks.

858ac19327 [renderer] Move r_screen and r_cvar into main bin 
r_screen because of SCR_UpdateScreen, and r_cvar because the cvars
really should never have been in a plugin in the first place (and
r_screen needed access).

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.

8f6f32981c [vulkan] Add some matrix buffers 
It seems they could all be in the one buffer: there are indications that
uniform binding can be fairly fine-grained. I need to investigate that.

6e636a27d0 [renderer] Continue the job of merging SCR_UpdateScreen 
I think this is probably as merged as it will get (though the update
callbacks can probably do with some merging).

23db917ec4 [vulkan] Create a staging buffer struct 
And move the barrier prefabs into a more convenient place.

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.

e7106cce9e [plugin] Remove Draw_Init from draw funcs 
It's never called outside the renderers.

b6d2c63059 [vulkan] Fix some formtatting 
Both code and developer output.

25ade4c0f3 [vulkan] Add support for custom parsers 
And provisionally parse shader stage defs.

0a0035e5e5 Use the render pass to clear the window 
Very satisfying to get to this point.

89d48b5650 Output first pixels 
Just clearing the screen to 0xbada55, but the validation layer is quiet.

94565c2382 Rework much of the Vulkan array handling 
So much for all those little wrappers hiding the device. Some survived,
but mostly just the bigger things like device, swapchain, etc.

916e57de37 Get the swapchain image switching sort of working 
The render pass isn't set up yet, so the validation layer is having a
fit, but cycling through the swapchain images does seem to be working.

559bd2e636 Create command pool and frame timing fences 
Nothing is actually done yet, so the reported fps is around 172k (yes,
k), but startup and shutdown seems to be clean (yay validation layers).

not sure how that one got through

75f19f7243 Completely rework the vulkan related api 
Things don't work yet, but this feels much cleaner.

Yay, segfaults in R_Init :)

b3d982bfc3 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.

8ee06d75a9 Separate render and presentation initialization 
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.

6ee2df8445 Move vid callbacks into vid_internal 
Currently segfaults because viddef is an alias for *r_data->vid, which
has not yet been initialized (chicken and egg).

77afc30486 Fix vid renderer plugin types 
I guess that plugin type is currently not checked, otherwise I doubt the
mistake would have gone unnoticed.

2bc78e7f0a 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.
