Summary: Mouse events broken

Description Will 2009-01-02 19:27:17 UTC 
SDL is not reporting which window a mouse event is cumming from (just reports 0).
Also the relative mouse position properties are broken in the mouse move event.
Comment 1 Will 2009-01-02 20:47:18 UTC 
Looks like the mouse wheel event also does not report which window.

More importantly the direction of the scroll wheel is always positive.
This is a trivial fix.

replace the following in "SDL_win32events.c":

                if (raw->data.mouse.usButtonData != 0) {
                    SDL_SendMouseWheel(index, 0,
                                       raw->data.mouse.usButtonData);
                }

with:

                if (raw->data.mouse.usButtonData != 0) {
                    SDL_SendMouseWheel(index, 0,
                                       (short)raw->data.mouse.usButtonData);
                }
