One definite problem I have discovered is that the width and height of 
the text returned by GetTextExtent() in the code above appears, 
according to debugging prints, to be (0, 0) on Ubuntu Linux, while on 
Windows I get definite sizes. When the background is non-black I do see 
(black) text, but this makes me wonder whether there's some font oddity 
or subtlety I have overlooked.
