Check for zero paper width or height #55

Closed hholzgra closed 2 years ago

hholzgra commented 2 years ago

A paper size with a width or height of zero leads to a 

ocitysmap.cairo.IOError: error while writing to output stream

while rendering, this should be caught up front with a more meaningful error message.
