If the functions need to be added anyway, isn't adding the terminal_shape
to pango easier than adding to libzvt? The layout engine for terminal 
can make use many of pango's services. 

Beside, if an application need to use some terminal like displaying, 
it can switch to terminal_shape without load libzvt.
