Viewer Freeze on Extraction of Static Objects

[ClintonButler]

I was just testing out your great little tool and found that the client completely hung about 1300 items in or so.

Thanks for the issue and trace.. Should be simple enough to fix up, I render static_objects with the client, so this was probably a porting bug.

@Wizbaggd give this another try. It turns out that the static objects trying to be rendered had 0 height (48 pixel width and 0 pixel height).

I check the static object height before saving now. This means that some objects may not export, but the viewer won't hang
