Pierre, fantastic news!
Regardless of the technology it would be nice to have general-purpose
Qt-only library i.e. provided as QImageIOPlugin, ideally maybe plus
some helper classes like QWidget and QGraphicsItem capable of
displaying the metafiles.
As for converting it's always a question of efficiency: if competing
code can render the metafile directly, we'll be slower having the
filter chain (the same as with document format filters).
But we can't we use QSvgGenerator to get option of conversion to svg?
