[SDL] mouse button/movement troubles

[John Drinkwater]

 From going through the code,
   SDL_WarpMouse resets the mouse states

Makes sense for most applications to have this as the default (lets say, you 
move off of one button onto another); yet there isn't an option to get it to 
either retain button state, or give it new ones.

Could you use the ignore (which i'm presuming you're using to stop the warpmouse 
event changing your mouse position again) to prevent the SDL_MOUSEBUTTONs 
getting triggered ?

John
