Not really. The grab size is set by setImageSize(). The grab() call takes a 
scale parameter but has an assert(!scale) in it. As I understood it, if scale 
is true, the grab call should scale the image up/down from a possibly limited 
capture size to the desired image size. This is what I wanted to remove.
