Fixed bug 3550 - No mouse move messages send while over the titlebar and windows edges 

Matthew

Its possible to set SDL_CaptureMouse() so you continue receiving mouse input while the mouse is outside your window. This works however There is then a gap where no messages send, which is when the mouse is hovering the title bar and the window edges.
