Ok this is what I've decided to do. In order to ensure that gtk2.c will work on
windows, I have decided to keep the fullscreen code separate.

There will be a fullscreen.h that defines the 4 functions that gtk2.c depends
on, and there will be a fullscreen "driver" of the name <library>_fs.c that
implements these functions.

I've written an xvid_fs.c which implements fullscreen mode via the Xvidmode
extension as well as a null_fs.c which doesn't do anything.

This way, Linux/FreeBSD/etc users can use the xvid_fs driver to get fullscreen
mode with gtk and Windows users can use the null_fs driver to use gtk mode.

The idea is that someone could implement a win32_fs driver that would enable
fullscreen mode in Windows. I do not know enough about win32api programming to
write this myself.

If gtk mode is enabled, the configure script will select the correct driver
by default (xvid_fs on unix, null_fs for everyone else) but there will be an
option to override this.

I have a few kinks to work out (plus some configure/Makefile diffs to write)
but expect a patch and the new files in a few hours.

On a side note, has anyone tried to use the gtk2 driver on windows? If so, can
you tell me what happened?
