Composite charts should pass filters to children

[jcamins]

It seems to me that if you have a composite chart, changing filters on the parent chart should change the filters on the children. Can anyone think of a reason not to have composite charts call their children's filter functions?

Yes... we have the following related issues: #390 and #677.

Unfortunately I haven't found the time/concentration to look closely at the problem yet. But @mtraynham reported that the obvious fix didn't work in all cases. A PR that addresses all three issues would be very much appreciated! (This is really the root issue and the others discuss some of the symptoms.)

Also, #682 implements filter sync for row charts; I plan to generalize this approach for 2.0. (The one new feature I plan to include, because of all these bugs associated.)

I think this was fixed a while ago but wasn't functioning correctly until #1408, released in 3.0.2

If I'm missing something, please let me know and I'll reopen.

This is the programmatic version of #1408 and still needs to be implemented.

Fixed by #1435 in 3.0.4
