error handling negative width/height

[GoogleCodeExporter]

default new_width and new_height are set if both are 0
As they are casted in integer, the check should also be done against negative 
values.

good idea. I have changed this so that the initial get_request is wrapped in an 
abs, which will always make the request positive (and reduces the if 
statements). Also wrapped the quality get_request for the same reason
