fteqw/engine/gl/gl_font.c
Spoike 811bce25f1 Too many changes, sorry. 
Change revision displays, use the SVN commit date instead of using __DATE__ (when there's no local changes). This should allow reproducible builds.
Added s_al_disable cvar, to block openal and all the various problems people have had with it, without having to name an explicit fallback (which would vary by system).
Add mastervolume cvar (for ss).
Add r_shadows 2 (aka fake shadows - for ss).
Add scr_loadingscreen_aspect -1 setting, to disable levelshots entirely, also disables the progress bar (for ss).
Better support for some effectinfo hacks (for ss).
Added dpcompat_nocsqcwarnings (because of lazy+buggy mods like ss).
Rework the dpcsqc versions of project+unproject builtins for better compat (for ss).
Added dpcompat_csqcinputeventtypes to block unexpected csqc input events (for ss).
Better compat with DP's loadfont console command (for ss).
Added dpcompat_smallerfonts cvar to replicate a DP bug (for ss).
Detect dp's m_draw extension, to work around it (for ss).
Cvar dpcompat_ignoremodificationtimes added. A value of 0 favour the most recently modified file, 1 will use DP-like alphabetically sorted preferences (for ss).
loadfont builtin can now accept outline=1 in the sizes arg for slightly more readable fonts.
Fix bbox calcs for rotated entities, fix needed for r_ignorenetpvs 0.
Hackily parse emoji.json to provide 💩 etc suggestions.
Skip prediction entirely when there's no local entity info. This fixes stair-smoothing in xonotic.
screenshot_cubemap will now capture half-float images when saving to ktx or dds files.
Fix support for xcf files larger than 4gb, mostly to avoid compiler warnings.
Fixed size of gfx/loading.lmp when replacement textures are used.
Added mipmap support for rg8 and l8a8 textures.
r_hdr_framebuffer cvar updated to support format names instead of random negative numbers. Description updated to name some interesting ones.
Perform autoupdate _checks_ ONLY with explicit user confirmation (actual updating already needed user confirmation, but this extra step should reduce the chances of us getting wrongly accused of exfiltrating user data if we're run in a sandbox - we ONLY ever included the updating engine's version in the checks, though there's nothing we can do to avoid sending the user's router's IP).
Removed the 'summon satan all over your harddrive' quit message, in case paranoid security researchers are idiots and don't bother doing actual research.
Removed the triptohell.info and fte.triptohell.info certificates, they really need to stop being self-signed. The updates domain is still self-signed for autoupdates.
Video drivers are now able to report supported video resolutions, visible to menuqc. Currently only works with SDL2 builds.
Added setmousepos builtin. Should work with glx+win32 build.
VF_SKYROOM_CAMERA can now accept an extra two args, setviewprop(VF_SKYROOM_CAMERA, org, axis, degrees).
Removed v_skyroom_origin+v_skyroom_orientation cvars in favour just v_skyroom, which should make it behave more like the 'fog' command (used when csqc isn't overriding).
Added R_EndPolygonRibbon builtin to make it faster+easier to generate textured ribbon/cable/etc wide lines (for TW).
sdl: Fix up sys_sdl.c's file enumeration to support wildcards in directories.
edit command now displays end1.bin/end2.bin correctly, because we can.
Finally add support for f_modified - though ruleset_allow_larger_models and ruleset_allow_overlong_sounds generally make it redundant.
Fix threading race condition in sha1 lookups.
Updated f_ruleset to include the same extra flags reported by ezquake.
A mod's default.fmf file can now contain an eg 'mainconfig config.cfg' line (to explicitly set the main config saved with cfg_save_auto 1 etc).
fmf: basegame steam:GameName/GameDir can be used to try to load a mod directory from an installed steam game. The resulting gamedir will be read-only.
HOMEDIR CHANGE: use homedirs only if the basedir cannot be written or a homedir already exists, which should further reduce the probability of microsoft randomly uploading our data to their cloud (but mostly because its annoying to never know where your data is written).
Fixed buf_cvarlist, should work in xonotic now, and without segfaults.
Added an extra arg to URI_Get_Callback calls - the response size, also changed the tempstring to contain all bytes of the response, you need to be careful about nulls though.
Try to work around nvidia's forced-panning bug on x11 when changing video modes. This might screw with other programs.
sdl: support custom icons.
sdl: support choosing a specific display.
Added some documentation to menuqc builtins.
menusys: use outlines for slightly more readable fonts.
menusys: switch vid_width and vid_height combos into a single video mode combo to set both according to reported video modes.

if we're loading for the fallback then we're loading this data for quake compatibility,
so we grab only the first 4 rows of each set of chars (128 low chars, 128 high chars).
if we're loading a proper charset, then we load only the first set of chars, we can recolour the rest anyway (com_parseutf8 will do so anyway).
as a final note, parsing iso8859-1 french/german/etc as utf8 will generally result in decoding errors which can gracefully revert to 8859-1 safely. If this premise fails too much, we can always change the parser for different charsets - the engine always uses unicode and thus 8859-1 internally.
