In addition to standard unit tests for functionality, we should set up testing which checks that images produced by routines with visual output are a precise match to a reference image known to be correct, for a wide coverage of applicable inputs.

In the codebase there are currently some limited tests of this description, which use ImageMagick to compare outputs with reference images. The coverage of these tests should be increased, but first I propose to change the means for image comparison.
