My panning widget uses the WidthOfScreen and HeightOfScreen macros to 
get the current screen size in pixels. They're both Xlib functions.

They will return the current size of the root window, so if you're doing 
something funky like me and having big virtual screen and a panned 
viewport, you won't get the viewport size, just the size of the virtual 
screen the viewport's moving about on.

But if you're just flicking between actual screen resolutions and you 
can see your entire desktop at each resolution change, they should work
