I looked into a regression with the icon layout code and this patch
turns out to be the culprit. It actually breaks the emblem bounds
calculation: Create two files in the icon view and give both an emblem.
Then zoom < 100%. There'll be a huge gap between the icons as the emblem
rectangle gets larger and larger (it's divided by a value < 1 after all)
as the zoom level decreases.
I don't think bringing pixels_per_unit into play at that point is right
at all but even if the calculation would be correct, it'd have to go
into update_bounds() too.

We'll have to revert that patch and try to find the real emblem drawing
bug (#104235), its symptoms were just masked by this change.
