I have a hunch that those would need weak references to work as
intended.  But I'm happy to let them leak for now.

Below is my patch for the scroll-bars.  I went for the indirection layer
solution.  Though, the mark-and-sweep pool idea might be more broadly
usable; with so many different GUI toolkits it's hard to say.

I also had a problem with the tool-bar, triggered by this test:
(dotimes (i 40)
  (igc--collect)
  (message "%S" (make-list i nil))
  (redisplay))

The third patch stops allocating glyph matrices as ambiguous roots.
Seems to work for me.
