Noted, thanks.  FTR, for dungeon I have several modes that are derived
from image-mode, e.g. for displaying graphical character sheets,
combat status information, and maps.  I also have a point-and-click
drawing mode for creating/editing "tile-sets" and composing (e.g.)
maps for dungeon levels using these "named SVG fragments".

I will look into these options. (So far, the change you made seems to
have all my stuff working again per the release branch.)
