Thinking a bit about this . . .

Use polygon objects, or a lot of math. But I think polygon objects would be simplest for hit-testing.

Polygon objects are always going to be better than blowing my brains with Mathematics.

It's effectively the same arithmetic, but done in the engine in compiled object code rather than via script. I've found that it takes a very large number of objects on a card to slow hit-testing below what would be needed if scripted instead.
