revision:	3566:9c16238ea418
author:		Evan Schoenberg

Noted in `AIVariableHeightOutlineView`'s header that _ai_drawRow:clipRect: is a correct drawRow:clipRect: override point, and then followed my own directions in `AIVariableHeightFlexibleColumnsOutlineView`. Fixes drawing in the Events tables. Fixes #14629
(transplanted from 22fb5f71ee728a1d6c4b7870fb256945e184d779)
