Sounds are not started if the window is unfocused,
regardless of sound_disabled.
Fixes -nosound not working (sounds would always be
reenabled if window comes into focus).
Downscaling is now performed during screen capture instead of GIF writing
This may or may not make GIF recording faster?
Maybe it would be faster if I knew how OpenGL worked...
Regardless, the m*th in the GIF code is gone, fixing the high/odd res issues
Also includes a little deduped hardware code, and GL 4.3 debugging code
* On GL, the background no longer disappears if the game is paused
* On GL, changing resolutions now draws SRB2BACK instead of a white void
* On software, changing resolutions redraws the level instead of awkwardly
stretching the background to fill the screen
Ultra mega hacked in, by saving all "discarded" joysticks to an array so they don't get totally closed & we can still poll them. Events now properly send the device number instead of the player number, which means we can store all controllers pressing buttons, and thus, can detect when ANY controller is pressing anything, and THUS we can make the character select work like we wanted to :V
Did not bother fixing any of the bugs, however. First of all, the opening menus do not properly fallback to default controls. Yet again, we may need a more robust system -- storing all keys from gamekeydown separately? Additionally it seems like when I input gamepad it makes me use keyboard anyway, so I think something fishy is up.
(G: finally, a commit that mostly survived... deviceResponding is useless
for us right now but might as well keep it. maybe easier assignment on
the multiplayer setup menu in the future?)
More or less a port with gamecontrols left untouched.
Some notable differences:
* ev_joystick now has a separate data1 for each axis, rather than having you
check which of data2/3 is INT32_MAX and which one isn't
(pissed me off when updating menu code...)
* Gutted the 1.6 upgrade code, since we're not upgrading from anything :P
* G_GetControlForKey, a helper for menu code
* Turn smoothing code left unused as a reminder to fix it
* Various small fixes so this commit is playable and doesn't segfault
Menu changes:
* Max 4 binds, joystick axes are now bindable like any other button
* The gamepad options submenu has been replaced by its two remaining options
after the removal of axis cvars (gamepad select and deadzone)
