For the thumbnail the code is rendering on a paper-like canvas, which is hard-coded as well (see lines above with `QColor ( 245, 245, 245 ); // light-grey background`). To simulate a print-out, for what I guess or would have done myself.
So with that using also a hard-coded theme should be fine, or?
