0a5981878b [sprite] Clean up field names and casting
No wonder I hated the sprite code: I couldn't see the code for all the
casts (and hungarian warts).

3a17e062da [renderer] Merge sprite billboarding code
As the sw renderer's implementation was the closest to id's, it was used
as the model (thus a fair bit of cleanup is still needed). This fixes
some incorrect implementations in glsl and gl.

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.

54604d9aa2 [util] Make hunk (optionally) thread-safe
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.

50740c1014 [model] Remove the confusion about numleafs
The fact that numleafs did not include leaf 0 actually caused in many
places due to never being sure whether to add 1. Hopefully this fixes
some of the confusion. (and that comment in sv_init didn't last long :P)

f47e03e606 [model] Remove 64k limit on visible leafs
Modern maps can have many more leafs (eg, ad_tears has 98983 leafs).
Using set_t makes dynamic leaf counts easy to support and the code much
easier to read (though set_is_member and the iterators are a little
slower). The main thing to watch out for is the novis set and the set
returned by Mod_LeafPVS never shrink, and may have excess elements (ie,
indicate that nonexistent leafs are visible).

Really needed only for vulkan, but removing currententity from gl and
glsl made testing easier.

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).

a05210d864 [video] Get 16 and 32 bit sw32 mostly working in x11
Lighting on alias models seems to be borked, and skies are borked in
both sw renderers (seems to be nothing to do with this commit, though).

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.

4b1eb0d760 [sw] Speed up Draw_FadeScreen
It now processes 4 pixels at a time and uses a bit mask instead of a
conditional to set 3 of the 4 pixels to black. On top of the 4:1 pixel
processing and avoiding inner-loop conditional jumps, gcc unrolls the
loop, so Draw_FadeScreen itself is more than 4x as fast as it was. The
end result is about 5% (3fps) speedup to timedemo demo1 on my 900MHz
EEE Pc when nq has been hacked to always draw the fade-screen.

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

39103cc8a3 [sw] Fix some 32-bit assembly issues
I'm not sure that the mismatch between refdef_t and the assembly defines
was a problem (many fields unused), but the main problem was due to
execute permission on the pages: one chunk of asm was in the data
section, and the patched code was not marked as being executable (due to
such a thing not existing when quake was written).

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).

now the flag definitions and names list will never get out of sync.

5bf21931c7 [renderer] Remove more old fields from entity_t
The only transform related field remaining is old_origin. This also
brings the renderer closer to using simd (lots of stuff to fix still,
though).

abaccbec53 [client] Move qw's loc code into client
This makes the location code available to nq (not used yet) but more
importantly moves some definitely client-side code into the right place.

fbc1bd9f6e [renderer] Clean up entity_t to a certain extent
This is the first step towards component-based entities.

There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.

As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.

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.

7970525ef4 [util] Make va thread-safe
It now takes a context pointer (opaque data) that holds the buffers it
uses for the temporary strings. If the context pointer is null, a static
context is used (making those uses of va NOT thread-safe). Most calls to
va use the static context, but all such calls have been formatted
consistently so they are easy to find when it comes time to do a full
audit.

7a19be7265 [image] Change tex_t data from array to pointer

goal was to be able to use tex_t with data that is in a separate chunk
of memory.

6d5ffa9f8e [build] Move to non-recursive make
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.

The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.

Most of the old Makefile.am files  are now Makemodule.am.  This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases).  The current remaining Makefile.am files are for
standalone sub-projects.a

The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.

While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).

8ee06d75a9 Separate render and presentation initialization
This paves the way for clean initialization of the Vulkan renderer, and

These are the ones where I could easily make scan-build happy. They do seem

bc12567572 Clean out a leftover from the 128 dlight change.
I'd missed a set of bit->lightnum conversions that resulting in lightnum

The seed is currently 0xdeadbeef, but I intend on fixing that soon. Now the

3de67589a3 Fix random particle origin/velocity z component.
This is a quick fix until I get a random number generator into QF.

Mingw's RAND_MAX is only 0x7fff and so the (((rnd >> 10) & 63) - 31.5) / 63.0
used for the z component of origin and velocity would never go positive.
For now, change the 10 to 9 (reusing another bit from Y). I plan on
implementing a full 32-bit PRNG in QF so we always have a reliable
generator.
