Subject: SDL: Relative mouse movements
The patch below will reenable processing of relative mouse movements.
The DirectFB drivers generates those in "grabbed" mode. These ensure,
that even in fullscreen mode relative movements are reported. SDLMAME
depends on this for games with trackballs.
Looking at the code I ask myself whether relative movements should be
handled in the drivers (x11, directfb). Both x11 and directfb are able
to report relative movements. This would leave it to the driver to use
the most appropriate method for relative movements when at the border of
a fullscreen window or being "grabbed".
