This is perhaps not very obvious given the naming, but see 6.1 - the  
'initial-scale' "variable" at this point in the procedure is not  
necessarily the same as the computed value. If it nevertheless is 'auto',  
the third sentence of 6.1 addresses that.

(I don't work with C++, but if the computed value of width is auto, what  
does qreal(appliedWidth) become in this case?)
