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.
Move r_pcurrentvertbase into the sw renderer, cleaning up gl's use of
(not really needed there). Not ready to move r_bsp into the main bin yet
as there are linking issues since only the low-level code references any
of its symbols.
Finally. I never liked it (felt bad adding it in the first place), and
it has caused confusion with function and global variable names, but it
did let me get the render plugins working.
Where possible, symbols have been made static, prefixed with gl_/GL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing.
sane now. Also optimize QSG2 color handling, and fix some QSG2 bugs. Not that
anyone cares, nobody uses it anyways.
Should be faster, but isn't here. *grmbl*
Now just have one (known) issue with bmodels with fullbright textures not
rendering their base texture. Floating fullbrights are nifty!
Also a number of optimizations, which need wider performance testing.
The major change is that we no longer require libGL to even exist on the
system at compile time for the GL targets, we dynamicly link to the
libGL of choice at run time. (This probably breaks most non-linux
systems, and all GL targets except -glx, some fixup will be needed.)
(This also kills glquake, dead dead DEAD! GONE FOREVER! WHEE!)
Some gl_draw cleanup.
Commented out equake alias model occlusion test stuff, very experimental.
Added the .lo and .la patterns to the .gitignore files.
Some minor sbar cleanup. (We don't use the disc in use symbol for
anything.)
