Michael,
Thanks for taking a whack at this. It's a feature that'll make a lot of
people happier.

This may not be that bad.
After drawing the entire run, scan the characters you just drew to see
whether any of them are spaces. If so, do another drawing pass which draws
dot characters "over" the space characters. Because we store the width of
each character, you should be able to position those dots correctly.

Do you want to draw all the way from the left of the page to the right? If
so, then take a look at how the calculation is done for drawing those fancy
drop shadows on each page:
FV_View::_draw()
IIRC, each page knows its own width, which is how the page decorations get
drawn.

Two suggestions:
1. Look in abi/docs in the source drop.
2. Look at the README files sprinkled around the tree.

You're doing fine. Anybody asking such detailed questions about specific
spots in the code is going to find their way around quickly enough. :-)
Welcome aboard!
