f5e39ba263 [renderer] Allow render config to be specified
The config is a pre-parsed property list. Currently unsupported by
anything but Vulkan (but only a warning is given, not a hard error at
this stage), and Vulkan doesn't use it yet.

fea08de4cb [renderer] Switch fog to be simple exponential
I don't know why exp(-dist^2) was thought to be a good idea, it's not at
all correct, and I think exp(-dist) looks better.

b22f104163 [renderer] Merge light setup code from glsl and sw
I'll look into gl later, but this means I don't need yet another copy
for vulkan's forward renderer.

63bec6d67f [scene] Add more entity component helper functions
Cleans up the code and removes more opportunities for UB.

0539f07c1a [skin] Use an ECS registry to manage skins
This takes care of the double free and also cleans up a lot of the skin
api. However, the gl renderer lost top/bottom colors (for now). Vulkan
skins still don't work yet.

c01c4180f3 [glsl] Handle verts with no bones
Same issue as in vulkan (surprise surprise, considering the glsl code
came first).

119e9766b9 [iqm] Use 32-bit indices for large models
That is, those with more than 65520 vertices. Not properly supported for
sw or gl, and glsl isn't rendering properly for some reason (renderdoc
does see the meshes, though, so maybe depth or winding issues).

860f48d541 Clean up about 12000 allocations
Some of them were actual leaks, but tracking memory should be a lot
easier now. However, there's a lot of room for optimization of
allocations (eg, recylcling of hierarchies. There is now 1 active
allocation (according to tracy) when nq exits: Qgetline's string buffer
(I think an api change is in order).

35eec0b2e5 [ecs] Implement hierarchies as components
The main goal of this change was to make it easier to tell when a
hierarchy has been deleted, but as a side benefit, it got rid of the use
of PR_RESMAP. Also, it's easy to track the number of hierarchies.

Unfortunately, it showed how brittle the component side of the ECS is
(scene and canvas registries assumed their components were the first (no
long the case), thus the sweeping changes).

Centerprint doesn't work (but it hasn't for a while).

650ea052ea [vulkan] Support clipping rectangles via scissor
Seems to work well. The other renderers have stubs because I don't feel
like implementing clipping for them. The gl and glsl wouldn't be too
difficult (need to handle the draw queues), but sw needs a fair bit of
work and I'm not sure it's worth the effort.

43cea64709 [renderer] Get trails looking vaguely acceptable
Still not great, but I like the falloff and the mixing is better. The
path offset seems to be unstable, so that needs work still.

34daf9032d [renderer] Get trails rendering again
They're not quite working (trail path offset is incorrect) but their
pixels are getting to the screen. Also, lifetimes are off for rocket
trails in that as soon as the entity dies, so does the trail.

c5731374cd [glsl] Separate out the trails implementation
This gets things *compiling* again, though it's still non-functional and
definitely wrong (don't want trail in renderer_t), but I need to think
about the design for getting trails as components. Also need to think
about integrating trails into the client effects system so trails can be
shared between renderers.

efea07f488 [gl,glsl,sw] Skip onlyshadows alias models
While the gl renderer does (or did) have it's attempt at shadows, the
others don't even try, thus the onlyshadows-marked player model doesn't
work so well (looks rather goofy seeing the arms like that).

f436806006 [scene] Remove full_transform from renderer_t
I've wanted to do this for a long while, but I finally got the
motivation to clean up the two uses in gl and glsl. Removes 64 bytes
from the struct.

35ec2ebb4c [scene] Move dynamic lights into the scene ECS
While the insertion of dlights into the BSP might wind up being overly
expensive, the automatic management of the component pool cleans up the
various loops in the renderers.

Unfortunately, (current bug) lights on entities cause the entity to
disappear due to how the entity queue system works, and the doubled
efrag chain causes crashes when changing maps, meaning lights should be
on their own entities, not additional components on entities with
visible models.

Also, the vulkan renderer segfaults on dlights (fix incoming, along with
shadows for dlights).

7e758327f6 [glsl] Use a unified queue for batched quads
This makes the glsl renderer compatible with canvases, and thus imui. It
also makes for much saner draw call counts.

585f1161db [renderer] Clean up R_MarkLeaves
Really? More to clean up before (vulkan) bsp rendering is thread-safe?
However, R_MarkLeaves was pretty close: just oldviewleaf and
visframecount, but that's still too much. Also, the reliance on
r_refdef.worldmodel irked me.

dbd3d6502a Nuke qboolean from orbit
I never liked it, but with C2x coming out, it's best to handle bools
properly. I haven't gone through all the uses of int as bool (I'll leave
that for fixing when I encounter them), but this gets QF working with
both c2x (really, gnu2x because of raw strings).

795021e229 [util] Record allocated blocs for ALLOC

ALLOC.

4e1ddaa964 [renderer] Add fitted pic rendering
The pic is scaled to fill the specified rect (then clipped to the
screen (effectively)). Done just for the console background for now, but
it will be used for slice-pics as well.

Not implemented for vulkan yet as I'm still thinking about the
descriptor management needed for the instanced rendering.

Making the conback rendering conditional gave an approximately 3% speed
boost to glsl with the GL stub (~12200fps to ~12550fps), for either
conback render method.

5668006087 [renderer] Replace Draw_FontString with Draw_Glyph
While Draw_Glyph does draw only one glyph at a time, it doesn't shape
the text every time, so is a major win for performance (especially
coupled with pre-shaped text).

95f55dfc34 [ui] Move text handling into gui lib
And add a function to process a passage into a set of views with glyphs.
The views can be flowed: they have flow gravity and their sizes set to
contain all the glyphs within each view (nominally, words). Nothing is
tested yet, and font rendering is currently broken completely.

136bf882f6 [ui] Move font loading into new gui library
Font and text handling is very much part of user interface and at least
partially independent of rendering, but does fit it better with GUI than
genera UI (ie, both graphics and text mode), thus libQFgui as well as
libQFui are built in the ui directory.

The existing font related builtins have been moved into the ruamoko
client library.

e0b9e118a0 [renderer] Remove the 1/2 pixel shift of the 2d screen
It seemed like a good idea at the time, but it exacerbates pixel leakage
in atlas textures that have no border pixels (even in nearest sampling
modes).

7e442a9019 [renderer] Correct crosshair sizes
I'm pretty sure they're meant to be 8x8 and not 16x16. Certainly they're

b1d7bad2e3 [renderer] Move call to R_ClearEfrags to SCR_NewScene
Probably more such should be moved, but efrags is on my mind. There's no
need for the call to be spread through all the renderers.

9f6c367fce [console] Resurrect console scaling
Currently only for gl/glsl/vulkan. However, rather than futzing with
con_width and con_height (and trying to guess good values), con_scale
(currently an integer) gives consistent pixel scaling regardless of
window size.

a07eccd5c7 [glsl] Fix some GLSL conformance issues
I'm not sure when things broke on my laptop (I thought I got warp and
fisheye working on my laptop), but it turns out things weren't quite
right, thus warp (and presumably fisheye) weren't working properly due
to GLSL errors that I only just noticed. This fixes water warp (and
probably fisheye).

db7f8a461e [ecs] Move ECS core into its own library
While the libraries are probably getting a little out of hand, the
separation into its own directory is probably a good thing as an ECS
should not be tied to scenes. This should make the ECS more generally
useful.

20c861027e [sw] Take advantage of the ECS for edge rendering
This fixes the segfault due to the world entity not actually existing,
without adding a world entity. It takes advantage of the ECS in that the
edge renderer needs only the world matrix, brush model pointer, and the
animation frame number (which is just 0/1 for brush models), thus the
inherent SOA of ECS helps out, though benchmarking is needed to see if
it made any real difference.

With this, all 4 renderers are working again.

2a9fcf4f5f [renderer] Tidy up entity component access
Since entity_t has a pointer to the registry owning the entity, there's
no need to access a global to get at the registry. Also move component
getting closer to where it's used.

8acd5c558b [scene] Make entity_t just an entity id for ECS
This puts the hierarchy (transform) reference, animation, visibility,
renderer, active, and old_origin data in separate components. There are
a few bugs (crashes on grenade explosions in gl/glsl/vulkan, immediately
in sw, reasons known, missing brush models in vulkan).

While quake doesn't really need an ECS, the direction I want to take QF
does, and it does seem to have improved memory bandwidth a little
(uncertain). However, there's a lot more work to go (especially fixing
the above bugs), but this seems to be a good start.
