c3f38e1c79 [renderer] Remove player_entity field
This was a hold-over from the gl mirror code.

2b72506868 [renderer] Handle transparent surfaces
Other than the view model (undecided on the approach) this has
R_RenderView pretty much pulled out of the low level renderers. With
this, I'll be able to focus on scene handling for a bit then getting
shadows and fisheye working (again for fisheye).

c05476f94b [renderer] Move most of the scene rendering into r_screen
r_screen isn't really the right place, but it gets the scene rendering
out of the low-level renderers and will make it easier to sort out
later, and hopefully easier to figure out a good design for vulkan.

91d7a80dff [renderer] Get timegraph and zgraph working
Only for sw and gl right now, but this sorts out the issues that
prevented the graphs working at all.

075a0fe326 [renderer] Clean up r_origin and modelorg
So far, in gl and glsl, but viewposition is much clearer than r_origin
(despite being the same thing), and modelorg is just confusing (I think
it's the view position relative to the current model).

48c225da89 [renderer] Merge the fog support code
GL still has its own functions for enabling and disabling fog while
rendering, but GLSL doesn't need such (thanks to the shaders), nor will
vulkan (and the software renderers don't support fog).

af0c66dff9 [renderer] Move frame rendering out a layer.
This is a step towards high-level unification of the renderers, as far
as possible keeping only actual low-level implementation details in the
individual renderers (some higher level stuff, eg shadows, is expected
to be per-renderer as some things are just not feasible to implement in
all renderers). However, the idea is to move the high-level
functionality into scene rendering.

ea2fd32228 [renderer] Merge screenshot code as much as possible
Only CaptureBGR is per-renderer as the rest of the screenshot code uses
it to do the actual capture (which is target dependent). Vulkan is
currently broken due to capture being an asynchronous process and the
rest of the code expecting capture to be synchronous (also, bgr vs rgb).

The best thing is all renderers now write the same format (currently
png).

d69355f521 [renderer] Support multiple entity queues
While there's currently only the one still, this will allow the entities
to be multiply queued for multi-pass rendering (eg, shadows). As the
avoidance of putting an entity in the same queue more than once relies
on the entity id, all entities now come from the scene (which is stored
in cl_world in the client code for nq and qw), thus the extensive
changes in the clients.

d70d72e6e4 [particles] Create a psystem object
This takes care of the global variables to a point (there is still the
global struct shared between the non-vulkan renderers), but it also
takes care of glsl's points-only rendering.

8d2791752e [particles] Merge particle spawning into client
After yesterday's crazy marathon editing all the particles files, and
starting to do another big change to them today, I realized that I
really do need to merge them down. All the actual spawning is now in the
client library (though particle insertion will need to be moved). GLSL
particle rendering is semi-broken in that it now does only points (until
I come up with a way to select between points and quads (probably a
context object, which I need anyway for Vulkan)).

ce4bb1d56c [renderer] Move particles over to simd
This has the advantage of getting entity_t out of the particle system,
and much easier to read math. Also, it served as a nice test for my
particle physics shaders (implemented the ideas in C). There's a lot of
code that needs merging down: all but the actual drawing can be merged.

There's some weirdness with color ramps, but I'll look into that later.

c5cfcc7bfd [sprite] Separate model and texture loading
As much as it can be since the texture data is interleaved with the
model data in the files (I guess not that bad a design for 25 years ago
with the tight memory constraints), but this paves the way for
supporting sprites in Vulkan.

84a24dbb34 [renderer] Make R_RenderView private
This is actually a better solution to the renderer directly accessing
client code than provided by 7e078c7f9c.

Essentially, V_RenderView should not have been calling R_RenderView, and
CL_UpdateScreen should have been calling V_RenderView directly. The
issue was that the renderers expected the world entity model to be valid
at all times. Now, R_RenderView checks the world entity model's validity
and immediately bails if it is not, and R_ClearState (which is called
whenever the client disconnects and thus no longer has a world to
render) clears the world entity model. Thus R_RenderView can (and is)
now called unconditionally from within the renderer, simplifying
renderer-specific variants.

4898a44263 [console] Hook up new input system
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).

The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.

keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).

91eeae5186 [qw] Clean up netgraph somewhat
The renderer's LineGraph now takes a height parameter, and netgraph now
uses cl_* cvars instead of r_* (which never really made sense),
including it's own height cvar (the render graphs still use
r_graphheight).

755ef524e4 [video] Use views instead of conwidth and conheight
conwidth and conheight have been moved into vid.conview (probably change
the name at some time), and scr_vrect has been replaced by a view as
well. This makes it much easier to create 2d elements that follow the
screen size (taking advantage of a view's gravity) which will, in the
end, make changing the window size easier.

e81d690b51 [input] Create QF input library using keys.c
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).

Fixes #8

0be609e0fd [util] Make PI_LoadPlugin always call general init function
As the root cause for #16 was something else, this fixes only the basic
cvar initialization, but does fix #19 (for now, at least).

02ff875cd6 [audio] Add optional on_update output function
on_update is for pull-model outpput targets to do periodic synchronous
checks (eg, checking that the connection to the actual output device is
still alive and reviving it if necessary)

db7e99d842 [audio] Allow output plugins to specify model
Output plugins can use either a push model (synchronous) or a pull
model (asynchronous). The ALSA plugin now uses the pull model. This
paves the way for making jack output a simple output plugin rather than
the combined render/output plugin it currently is (for #16) as now
snd_dma works with both models.

fc907e232f [audio] Rework alsa to use a pull model
This brings the alsa driver in line with the jack render (progress
towards #16), but breaks most of the other drivers (for now: one step at
a time). The idea is that once the pull model is working for at least
one other target, the jack renderer can become just another target like
it should have been in the first place (but I needed to get the pull
model working first, then forgot about it).

Correct state checking is not done yet, but testsound does produce what
seems to be fairly good sound when it starts up correctly (part of the
state checking (or lack thereof), I imagine).

37d35811e3 [vid,render] Clean up fov and aspect
vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).

91e3769c05 Recalculate the fov when the cvar changes.
This separate the FOV calculations from other refdef calcs, cleaning up the
renderer proper and making it easier for other parts of the engine (eg,
csqc) to update the fov.

34dc7cf2df [models] Move brush data into its own struct
This is a big step towards a cleaner api. The struct reference in
model_t really should be a pointer, but bsp submodel(?) loading messed
that up, though that's just a matter of taking more care in the loading
code. It seems sensible to make that a separate step.

r_screen because of SCR_UpdateScreen, and r_cvar because the cvars

r_screen needed access).

The gl renderer calling sw functions is bad news. Still all black, but I

d62772e9cc Separate render module loading from initialization.
This allows the vid module to load the render module and access render

an initialized vid module...
