Bug#290392: view fullscreen also doesnt use correct sizes

[Siward de Groot]

I use vlc as audio player, for net radio.
If i press button "View", it pops a menu,
and if i then select "Fullscreen Interface", size of interface becomes that of 
entire virtual desktop.
I use a larger virtual desktop size than fits on my screen
(so i can easily make the docking area invisible).

I do not know whether this is the same bug as Bas reports,
but i think it has the same fix :
scan the entire sourcecode for any use of functions XDisplayHeight or 
XDisplayWidth,
and if the source is C, also scan it for use of macros DisplayHeight or 
DisplayWidth,
and replace that by some appropriate function of the xvidmode extension.
