Apparently the root window changes in this case. We want to send to the root window that is being listened to by the window manager, so this should be okay.
When programmatically resizing a window on Unity 3D, we'll get a move event with the old size before we get a size event with the new size, and we don't want to clobber our internal state with the old size.
2.Replaced XKeycodeToKeysym with XkbKeycodeToKeysym since XKeycodeToKeysym is deprecated in newer X11 version
3.Rewrote testime.c since it was disabled after SDL_compat.c removal
4.Take into account common arguments also in testrelative.c
1.initial work on XInput2 support
2.Implemented relative mouse motion when XInput2 is enabled
3.Created a test app to test relative mouse motion
4.Fixed Bug #1498

On X11, SDL 1.3 does not generate a mouse wheel event. Instead, button
down/buttton up events are generated by SDL. After looking at the code in
SDL_x11events.c, I assume this is due to the fact that X11 does not have a
dedicated mouse wheel event.
I did a little research on the behavior of mouse wheel events on X11 systems.
Apparently, mouse wheel events generate a button down/button up event with the
same time, i.e. with exact same timestamp.
Attached you can find my changes to SDL_x11events.c, which generates SDL mouse
wheel events for those button down events that have a button release event
immediately following it (for the same button, and with the same timestamp).
I did have to make an assumption: As standard X11 implementations know only 5
buttons, I have mapped Button4 to "wheel up" (i.e. +1), and Button5 to "wheel
down" (i.e. -1).
Note that if you include this patch, no SDL button down/up events will be
generated on X11 platforms for mouse wheel events (which is probably a
significant change for those that have programmed their code to work with
them).
You can also do this through the native API:
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
Also needed to name the union for events and window info.
Unfortunately, this doesn't work. I also noticed that maximizing doesn't work as well. Also xprop hangs when trying to list properties of SDL windows.... ???
As far as I know there isn't any real way to tell when the clipboard contents have changed without polling them, so I didn't implement the clipboard update event on X11.
Fixed a bug where only mouse wheel up was sent on Mac OS X
Fixed a bug where mouse window focus was getting hosed by the fullscreen mouse code on Mac OS X
