Ideally, we should be targeting Direct2D on Windows, only falling back 
to GDI+ for older operating system version (before Vista).

Cairo uses GDI+ on Windows by default.
It looks like Mozilla wrote a Direct2D backend for Cairo, but I can't 
seem to find out if it was ever integrated back into the main Cairo 
library ( is currently unreachable for me).
