It's easy enough to substitute a different font in the call to
Imagemagick's `convert` tool, but in the case of pixel fonts, it will
scale them, so you're not getting a proper bitmap of the pixels, you're
getting a kind of screenshot of the pixels.
I want to make a different machinery for bitmapped pixel fonts, and I
want to make a simple DEFINE-based way to pick them without having to
edit your source code, e.g. #define font_data font_PublicPixel_22_data
yeah?
After that, simple affine transforms for fake 3D..
