/*
SCREENSetMouseHelper.c
AUTHORS:
Allen.Ingling@nyu.edu awi
mario.kleiner@tuebingen.mpg.de mk
PLATFORMS:
All.
HISTORY:
12/14/02 awi Created.
10/12/04 awi Changed "SCREEN" to "Screen" in useString.
11/16/04 awi Added "Helper" suffix.
11/18/04 awi Renamed to SetMousHelper from PositionCursorHelper
DESCRIPTION:
Position the mouse pointer
TO DO:
-The hidecursor.m script should be modified to invoke hidecursor through screen only on OS X. On other platforms it is a
separate mex file.
-If we store a pointer to the window and screen lists in shared memory (accessible between mex files) then
we could implement this a a seperate mex file. Seems more natural to do it from SCREEN though. Let's wait and
see what Windows and Linux are like before changeing it to a separate mex file.
-Since all that we pass to the underlying CoreGraphics call is a screen ID, maybe we don't in face need to
have opened an onscreen window to more the mouse pointer. Test that. We will have to have enumberated the
displays though.
