Raw Blame History

//Generic input code.
//mostly mouse support, but can also handle a few keyboard events.
//Issues:
//VirtualBox mouse integration is bugged. X11 code can handle tablets, but VirtualBox sends mouse clicks on the ps/2 device instead.
// you should be able to fix this with 'in_deviceids * 0 *', remapping both tablet+ps/2 to the same device id.
//Android touchscreen inputs suck. should have some onscreen buttons, but they're still a bit poo or something. blame mods for not using csqc to do things themselves.
