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..
ooo that's a finicky parser tho
Early days. It's all good.
(But damn those Rust tracebacks, what a useless pile of text. i know
the problem is in the parser!? why is it showing me all the rust
internal crap and none of the actual stack trace of the ncc code? I
mean, look at this thing:

gmake: *** [GNUmakefile:11: /home/sforman/src/uvm/ncc/out.asm] Error 101
There's ONE LINE from the ncc source: uvm/ncc/src/main.rs:98:20 which is a call
to parse_unit, but it's the following unwrap that seems to be causing the error
message?
