I added Sys_RegisterShutdown years ago and never really did anything
with it: now any system that needs to be shutdown can ensure it gets
shutdown on program exit, and in the correct order (ie, reverse to init
order).
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
This fixes the segfault and pushes things very much in the desired
direction of proper system independence for rendering and presentation
separation (though things were headed in the right direction before).
This fixes the status bar refresh issues in sw. The problem was that with
two viddef's hanging around, things got a little confused and recalc_refdef
wasn't getting into the renderer.
It seems that SDL_SetColors causes a page flip, so VID_SetPalette only
queue a palette change (by checking for the need to change and storing the
requested palete) and VID_Update now checks for a queued palette change and
updates SDL's palette if required. This fixes the flickering console in sw
-sdl introduced by the cshift/centerprint change.
This allows the vid module to load the render module and access render
specific functions before the renderer initializes, which happens to need
an initialized vid module...
Still, nothing will work: no plugins are loaded and they're all broken
anyway.
glx, sgl, glslx etc are going away, just the basics will be built: fbdev
(probably go away eventually), sdl, x11 and hopefully someday win. That's
actually the only reason anything links.
networking support.
Second, I moves keys.c from qw and nq to libs/video/targets when I did
the next thing.
Existing user configs which do binds, sledge hammer. Sledge hammer,
existing user configs which do binds. *WHACK* *WHACK* *WHACK*
See, much nicer now.
Someone should document it, and fix all targets which don't use SDL for
input. (I honestly don't expect svgalib and the like to ever be fixed.)
Don't bother checking vid_gamma for CVAR_ROM becuase it is impossible to
get to VID_UpdateGamma when it is set except for when the cvar is
initially created, and we /want/ the code to execute in that case.
vid.h:
add initialized to viddef_t
vid_common_gl.c:
actually /use/ gammatable (it tends to help)
vid_*.c:
clean up rendundant decls of gammatable, vid_initialized (now
vid.initialized) and make sure vid.initialized gets set.
gl_view.c:
remove gammatable decls
