Are these all classes that are actually allocated on the heap with new? The idea that we heap-allocate FloatQuad, FloatRoundedRect, and IntSize, for example, surprise me.

Do we have some good system for catching when we forget to do one of these? In the past I had wanted to come up with some trick with global allocator new to catch in the debugger if we miss one of these.

Why this change?

Looks like this class should be a struct.

"handels"

I assume this is because I finalized the class and the destructor now gets called directly at once of the call sites.
