on my computer it seems
like only IFDEF GTK_ENABLED code compiles
while GTK1 or GTK2 blocks are left out, is this a coorect situation?

I'm mainly intersted in the full screen mode :
1 is the separate window created by the plugin or
2. is it created by sending command to mplayer through slave mode,
   as if the user clicked 'f'

I have to put animated gif above the player,
which worked fine when resizing the widtget without fullscreen
