Attachment 636359 [details] [diff] uses aViewport.width/aViewport.height in setViewport, neither of which actually exist (sorry) - as it turns out, the function they call with these values still does something sensible (hurray), but instead, we should use the right values. This seems to have no obvious ill effect, other than an annoying message in the log. Patch incoming.
Created attachment 640642 [details] [diff] [review] Don't use properties that don't exist Calculate the viewport width/height first and use those variables in both places it's expected.
