New Revision: 57

Log:
2008-01-22 Carlos Garnacho <carlosg gnome org>
* plugins/mouse/gsd-locate-pointer.c: Reworked, add a more appealing
animation if there's a composite manager present, also use a similar
animation for the non-composite case, so most of the code is shared.
* plugins/mouse/gsd-timeline.[ch]: New files, object to control the
"locate pointer" animation.
* plugins/mouse/Makefile.am: Added these files to build.
