[mythtv] New mythgallery gl transition patch (zooming blend)

[Mark Dobossy]

If any mythgallery users out there could please give my patch a  
whirl, and give some feedback, I'd appreciate it.  It is simply a  
modified version of the blend (gl) transition, that zooms/fades out  
the previous picture, as the new picture fades in.  The patch file  
adds the new transition- it will be in the mythgallery settings, and  
is called "zoom blend (gl)".  The patch is attached to ticket #490:  
http://cvs.mythtv.org/trac/ticket/490 .  Any feedback would be great!
