I'm pretty sure you're interpreting this incorrectly. Instead, it
sounds like you should, when given a proposed rectangle, move the left
edge of that rectangle to where the text may begin for your shape, and
then split that rectangle where the text may end. The framework will
then recursively invoke your method on the remainder rectangle until
it equals NSZeroRect.
It's a standard greedy approach that should require no context.
