turns out the if the console is opened while no game is currently
running, cls.key_dest is not key_console but still key_game.
Changing it to key_console in those cases blows up in interesting ways.
So in Char_Event() we send events to the console in those cases.
The first row of AZERTY-Keyboards (used in France and Belgium) doesn't
have numbers as keys but ², &, é, ", ', (, -, è, _, ç, à, ), =
(with small differences between France and Belgium).
For some of those keys we don't have keycodes - and neither does SDL2.
See also https://bugzilla.libsdl.org/show_bug.cgi?id=3188
As a workaround, just map those keys to 1, 2, ..., 9, 0 anyway, as those
are keys Quake2 already knows (and those chars are printed on the keys
too, for typing they're reachable via shift).
This workaround only works for SDL2, as SDL1.2 doesn't have scancodes
which we need scancodes to identify the keys.
While at it I unified handling of SDL_KEYDOWN and SDL_KEYUP, the code
is almost identical anyway, apart from one bool argument to Key_Event().
We track this problem in #81
This clamps the UI scale, limiting the relative size of the UI
elements to what they would be at scale 1 in a 320x240 resolution.
Allowing bigger scales is not useful, and would make it possible
for the user to shoot him-/herself in the foot by setting a
"too big" UI scale value in the menu. (Since this would mess up
the menu, it could be hard te recover from for a casual user.)
Because setting both a default target directory and a configuration specific target directory wouldn't work as intended with multi-configuration generators.
AL_PlayChannel() is only called by AL_AddLoopSounds() and
S_IssuePlaysound() - but only the latter set a volume there.
Because of that, loopsounds weren't hearable anymore after the last
commit which removed adding s_volume to all volumes in AL_PlayChannel().
This is fixed by setting the volume for looped sounds in
AL_AddLoopSounds() as well.
Looped sounds don't seem to have a customizable volume and are always
played at full volume (the volume is only changed by distance, but
OpenAL does that automatically).
The CD music enable / disable box wasn't used by many users for two
reasons: CD music playback needs a CDROM drive with analog output.
Such drives aren't available for at least 10 years. And CD music is
unsupported with SDL2. A OGG volume slider is much more usefull.
Con_DrawConsole() assumed that the version string was always 21chars
long, we changed it to allow longer strings with other lenghts.
In Unix main() we changed the code for underlining
"Yamagi Quake II $version" with === so the underlining is as long
as the underlined string.
