which really touches on whether "simple-draw5" or some future WIP will just
use a scene graph for everything anyway ...

simple-draw4 targets 3.10, its not very large:
  23 files changed, 1274 insertions(+), 2212 deletions(-)

But, the long term for Gtk4 is to move to a scene graph based on clutter.
and finally, does simple-draw4 attempt to work hard on behalf of particular
widgets, or is complexity left to the widgets? i think it is far preferable
to go the latter route, although there may be a small cost of duplicated

All complexity is left to the individual widgets, although there is a helper
object to share code.
