New function ggiFlushRegion()

Hi,

a new function has been added to LibGGI:

/* Flush only the specified region if it would improve performance */
int ggiFlushRegion(ggi_visual_t vis, int x, int y, int w, int h);

As the comment suggest it's exactly the same as ggiFlush() except
that it will only flush the specified region on targets that can
do this - like the X target. On other targets it is identical to
ggiFlush().

This is very good for applications which are not constantly updating
the whole screen - ie most non-games, and some games also.

Currently only the X target takes advantage of the new fumctionality,
but targets like palemu and trueemu could also be improved to use it.
