What library functionality would you most like to see in D?

[Adam D. Ruppe]

I've been thinking about a minimalist drawing library for
phobos - just basic 2d stuff, but with easy enough hooks to
add more (native api events and handles.

Nobody is likely to agree on a widget set, but basic drawing
functions give a little usability with pretty small cost.

I had a decent start a month or two ago but have since stalled out
as my schedule became more ridiculous.
