don't bother, you've much more important things on your plate.

This is a tiring bug in DDoc. I mean, why does it not generate a doc with a
missing parenthesis?
(I guess that's filed as bug 3554)

Halas, not from me: I'm at the same stage than you. At max, I'd know how to
draw a graph on an empty bitmap, as long as it can be done by lighting
individual pixels. And then saving it to disk.  But putting text in it (with
D or any other language) is beyond my ken.

I used this technics for a ray-tracer in D and for drawing L-systems, to
learn D :-)
In fact, the only way I found to save the raytracer images to disk was to
manage them as a an array of ubyte[3] and writing this to disk as a 24-but
RGB .bmp file.

I'll let Win32 wizards answer...
