BTW, I'm not really sure this is related, but we actually have been  
investigating font measurement for wxWebKit recently, and I noticed  
that on GTK w/wxDC, GetTextExtent returns the actual string size, not  
the "bounding box" needed to render the string. This is not the case  
with Mac and Win (w/wxDC or wxGraphicsContext), which do include the  
"bounding box".
