DNS does something like the following:
* Create a bitmap in ARGB format.
* Draw on the bitmap.
* Draw the bitmap on the window.

The problem is that we do our drawing with gdi32, and gdi32 doesn't really
support drawing on an ARGB surface. So all alpha values end up at 0, and we end
up drawing a transparent bitmap.

To fix this properly, we need the ability to draw without relying on gdi32.
