92afe9f265 [vulkan] Convert stagebuf to a ring buffer 
I should have known this would be necessary, but it fixes the corruption
when updating the scrap.

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.

cef81741eb [vulkan] Implement most of the 2D renderer 
The console background is missing, and scaled vs unscaled (currently
always scaled) 2d, but otherwise everything seems to work. Lots of
places to clean up, though.

41b3661869 [vulkan] Use the scrap for draw 
Draw now has its own staging buffer to use with its scrap. Also, a few
fixes were needed for the staging buffer and scrap flush routines.

Other than some synchronization issues with draw scrap flushing
(currently worked around with a fence-wait) things seem to be working
nicely.

eebf3158fa [ruamoko] Check for null when allocating objects 
It's difficult for progs to check for errors when the engine crashes out
from underneath them :P

a7ac188d1d [vulkan] Use a scrap texture for draw 
The scrap texture did very good things for the glsl renderer and the
better control over data copying might help it do even better things for
vulkan, especially with lots of little icons.

b6bc8ed553 [renderer] Move core of scrap into shared code 
The actual 2d area management code is now shared, with the actual
definition for scrap_t being left to the renderer specific
implementation.

bfbfd7af61 [glsl] Remove subpic_t's tnum 
It's never actually used (the texture can be fetched using
GLSL_ScrapTexture) and gets in the way of sharing the scrap system with
the vulkan renderer.

db14025935 [gamecode] Put strings and debug back in load funcs 
It turns out they're required to be initialized before most of the rest
of the system.

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).

93aa038d9e [vulkan] Generate handle get functions 
Cleans up (hides) the casting when fetching a handle.

8a85b5c610 [vulkan] Switch to float/normalized for pics 
It gives better results when pics are squished or expanded.

03f614ccb9 [vulkan] Parse VkBool32 correctly as bool type 
This makes it much clearer whether something is just a flag or an index
of some sort.

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).

88d48944cb [vulkan] Upload the default character set 
Nothing's shown yet, and the code is a tad messy, but it's serving as a
proof of concept for now.

b584d6f403 [vulkan] Abandon image "preinitialized" layout 
Turn's out it's not useful for transfers. I might bring it back when I
figure out how to use it.

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.

fd07169a80 [util] Support casts from int/uint to size_t 
I don't want to do implicit down casts (size_t to uint) but I needed to
be able to reference swapchain array size.

e281b608e1 [vulkan] Provide access to swapchain image count 
This necessitated hand-writing qfv_swapchain_t's descriptors as I don't
feel like getting that complicated with vkgen at this stage and it's not
really appropriate anyway? qfv_swapchain_t is meant to be read-only and
not parsed from a plist.

5aa74df922 [renderer] Add a default 8x8 font 
It is not compatible with the quake charset (it's the IBM charset). The
data is a simple bitmap but a converter to quake pic format is provided.

90428db3d5 [glsl] Remove stray return statement 
I have no idea why that was in that patch and certainly does not seem to
be correct.

5eb1afdcb3 [vulkan] Implement pipeline creation 
The prototypes for handle parsers needed to be changes because it turned
out "single" was inappropriate for handles as "single" allocates memory
for the parsed object, but handles must be written directly.

0da99bc59c [util] Add promotion from float to int to cexpr

a45f8f98b6 [util] Make exprctx hashlinks double pointer 
The way I wound up using the field meant that exprctx should not "own"
the hashlinks chain, but rather just point to it. This fixes the nasty
access errors I had.

d8b389d2b6 [vulkan] Initialize sType in parsed structures 
This fixes a lot of validation issues, but still some fun with
uninitialized memory and bad accesses.

3cf8a336a8 [vulkan] Clear out the resource tables on shutdown 
This would take care of undestroyed resources if there wasn't a problem
with invalid memory use. Not sure what's going on just yet.

layouts.
