Thanks to those who replied to my query about how to superimpose a guide
grid on a window without having the grid saved when I saved the finalk
image.
The answer is of course to keep a copy of the iamge with "canvas=hidden"
which does *not* have the grid, and save this copy rather than the on-screen
image. This is a little tedious (every graphics operation except the drawing
of the grid has to be performed twice), but it seems to work...
