recompute entire layout on mouse release

Recent changes have made the driver much more responsive, but it's also resulted in never ever updating the box model. One quick hack to provide some control here: panning the surface (or moving a definition) updates everything. And to remain snappy it only does so on mouse release.

I still need to polish when we recompute. Arguably we need to decompose A into a few different concerns and create variants that perform subsets of A's concerns. But this hacky commit helps.
