Grid size are not affected by edge label length

[user202729]

e.g. in the double limit in #206, several edge labels overlap on each other.

(This is not an easy problem though. If an edge spans multiple rows and columns, it's not clear which column should be enlarged.)

This was a deliberate design decision, for the reason that the desired behaviour is unclear, as you point out. However, it would be nice if there was some facility for manually increasing column/row sizes.
