Add a couple of regression tests for float fragmentation.

These tests change the fragmentainer heights, so that the float will fit in the
first fragmentainer afterwards, rather than in the second one.

Not sure if I'm going to be able to let floats use the fragmentation layout
optimizations that I'm working on. Floats are tricky, in that they are laid out
before they are positioned, which is painful when trying to figure out how
things will be split across pages or columns.

But anyway: here's a couple of evil tests for it.

Excellent! LGTM
