Follow-up Comment #1:

I can confirm a performance regression from 4.4.1 to 5.0.91, with qt as well
as gnuplot toolkits. With 1024 points, scatter3 takes about 20 seconds for me
with the qt toolkit, about 10 seconds with the gnuplot toolkit. Almost all of
the time is spent in the '__go_patch__' function according to profshow.
