Fixed.  http://dsource.org/projects/scrapple/changeset/772

I fired up my barely-used Linux partition for this.  I knew it would come in
handy.  I also kludged around the weird text cutoff bugs that only appear on
Linux.  (I don't want to say I fixed it because I didn't address the root cause
and I don't know what the root cause is.  My best guess is that on Linux the font
measurements are slightly off.)

The most serious bug now, IMHO, is that there's no way to save plots to a file
from a machine with console-only access, such as a supercomputer that you SSH
into.  I don't know how to fix this.  Calling Main.init() on a machine with no
windowing system borks everything.  Does anyone have any suggestions on how to fix
this?

In general, I want to thank the D community for answering my sometimes naive
questions about gtkD and GUIs in general.  Writing this plotting library has been
more challenging than most of my projects, as I'd never written a serious GUI app
before and am learning how GUI frameworks work on the fly.
