No, the sizes are needed to render correctly the base size, you can ask for 
any size you like. The desktop file contains the card size, so you can use 
that to have the "preferred" size, or scale it as you whish. That information 
is redundant, actually, since you can also use 
QSvgRenderer::boundsOnElement(name) 
to obtain the design size of any card.

Ok, I'll put it together this weekend, then.
