yep. If you check the git history: For the first prototype I passed
around a   "cairo_surface_t *"  that had the advantage/disadvantage that
pixman managed lifetimes. After some discussion with Filipe, it changed
into compatible ARGB.

Right now there are some caveats when using the raw ARGB32 data pointer
directly (see
http://cairographics.org/manual/cairo-Image-Surfaces.html#cairo-image-surface-create-for-data)

The hard part is not drawing but event handling. That's the main reason
why I kept it "display only".

apart from that, it'll be at least 2030 until MSVC adapts the C++
standard :)
