Okay, so that's actually Cairo with the win32 back-end. Surprisingly, using the two together is quite simple. I had to convert the cairo headers, do a little tweaks to help HTOD out, used implib with /s on the DLL, grabbed two other dependencies and ported a Python example to D. And it runs! Pretty cool having native windows controls and Cairo for smooth antialised graphics (with no flicker!). FWIW there's an object-oriented D1 wrapper for Cairo called CairOO, but it's severely outdated and the old dependencies don't even exist anymore.
