It seems like it would be near-impossible to do in a cross-platform way.

> Normally you will get warning(s) accompanying that Error ...
> Warning: unable to allocate bitmap
> Warning: opening device failed

Yes, I saw those but omitted them from the question.

That explains it.

> Try the other 2 types: the cairo devices do not use your graphics hardware nor MicroSoft's GDI.

Indeed, it works with the cairo backend.
