Only send mouse events if both values are non-zero.
Hopefully this helps with the event overflow spam that can sometimes
happen on loads or laggy situations.
SDL1.2 branch disables key repeat when key catcher is 0.
Presumably to prevent binds from executing multiple times.
SDL2 replaced being able to disabled key repeat using SDL_EnableKeyRepeat
with a non-zero repeat value in the key event.
UI VMs expect a backspace char event, but sdl2 branch only was only sending a key event.
Revert cl_keys.c to master branch (it would cause backspace to happen twice in console).
Quiting SDL Video or Joystick subsystem implies quiting the Event subsystem in SDL2.
SDL keeps track of number of init and shutdown calls for each subsystem.
Shuting down video or joystick more or equal to number of times they're inited will lead to event shutdown.
Toggling in and out of fullscreen or running in_restart twice causes SDL event subsystem to shutdown, making input not work.
If the console is closed, IN_GobbleMotionEvents gets stuck in a loop. SDL_PeepEvents returns -1 when there is an error, but we assume non-0 means read more events.
IN_ShutdownJoystick needs to check if joystick subsystem was inited before quitting it, otherwise we may cause SDL event subsystem to shutdown.
Make 'b' variable an int so that key values more than 255 will work (not currently an issue in ioq3 afaik).
Use SDL_BUTTON_* for easier transition to SDL2.
(SDL2 doesn't have SDL_BUTTON_WHEELUP or SDL_BUTTON_WHEELDOWN, X1/X2 are different values.)
* differing screen resolutions and network settings are now honoured when changing fs_game
* Fix hunk memory leak on game_restart
* Move cls.state and cls.servername to clc so connection state is fully preserved over game_restart
* Revert back to previous fs_game after disconnecting from a server that triggered a game_restart
* Fix error dialog popping up after every game_restart if an error happened previously (reported by Ensiform)
- Fixed that not all commands added by CL_Init() would be removed by CL_Shutdown()
* Fixed some whacky indentation in q_shared.c
* Allow single character keys e.g. 'c' to be used in cl_consoleKeys in addition
to ASCII characters
* Experimental code to ignore dead keys
