Fix Version: 1.3-current (r9216)
Should be fixed in r9216.
Leaving this open to see how it goes.
I tested with the attached code (tree-100k.cxx) that creates 100k items
which is entirely unusable in r9215 and lower, but should be
quite normal in r9216 and up.
There is still a practical limit on the number of items that
can be in the tree; draw() will still /consider/ (ie. do calculations
on) items that are not hidden (ie. open() and visible()), but at least
it won't try to /draw/ items unless they're inside the window.
