Spoike a6ac015c5b software banding: fix player skins. 
try to get game controller defaults a little closer to QS.
mess with r_dynamic 2 a little, to more closely match vanilla.
fix under-lighting bug on models. added extra model lighting pathway for greater vanilla compat, as part of software-banding.
fix proquake-client compat issue.

/*
X11 is a huge pile of shit. I don't mean just the old x11 protocol, but all the _current_ standards that don't even try to fix the issues too.
Its fucking retarded the crap that you have to do to get something to work.
timeouts to ensure alt+tab between two apps doesn't fuck up gamma ramps is NOT a nice thing to have to do.
_MOUSE_ grabs cause alt+tab to fuck up
if I use xinput2 to get raw mouse events (so that I don't have to use some random hack to disable acceleration and risk failing to reset it on crashes), then the mouse still moves outside of our window, and trying to fire then looses focus...
xf86vm extension results in scrolling around a larger viewport. dependant upon the mouse position. even if we constrain the mouse to our window, it'll still scroll.
warping the pointer still triggers 'raw' mouse move events. in what world does that make any sense?!?
alt-tab task lists are a window in their own right. that's okay, but what's not okay is that they destroy that window without giving focus to the new window first, so the old one gets focus and that fucks everything up too. yay for timeouts.
to allow alt-tabbing with window managers that do not respect requests to not shove stuff on us, we have to hide ourselves completely and create a separate window that can still accept focus from the window manager. its fecking vile.
window managers reparent us too, in much the same way. which is a bad thing because we keep getting reparented and that makes a mess of focus events. its a nightmare.
the whole thing is bloody retarded.
none of these issues will be fixed by a compositing window manager, because there's still a window manager there.
