Follow-up Comment #6, bug #52584 (project octave):

In order to make progress we probably need to go through the engineering cycle
of design/build/test.  And the number of iterations through that cycle is
limited if it takes 15 minutes to test each new change.

A simpler example of the problem is

x = linspace (0,1, 1e3);
plot (x,x, '.')
tic; print foo.png; toc

This takes 8 seconds on the development branch with FLTK, and 0.5 second with
QT.  I've attached the m-file as tst_slowprint.m.

(file #42573)
