Yup, that ought to do it, instead of trying to match only the window's
origin / top left corner. If it works as expected, at least. ;-)
static void screen_xywh (int &X, int &Y, int &W, int &H,
int mx, int my, int mw, int mh)
Gets the screen bounding rect for the screen which intersects the most
with the rectangle defined by mx, my, mw, mh.

The second step (adjusting the window to be entirely within the
screen) would then be the same.
Tried it - that was soooo easy! :-)
I'll commit it right after posting this message...
