Should hit-detection for complex shapes be based on bounding box or opaque regions?

[joshuahhh]

Text just uses the bounding box. But when I added Image, I included fancy hit-detection which doesn't recognizes hits from transparent parts of the image.

This seems needlessly inconsistent. Which should we use?

It feels very weird not being able to pick up an item when you click on transparent areas, as with Image right now.

I say use bounding box.
