make hopping thickness equal to hopping length^-2 when plotting (!240) · Merge requests · kwant / kwant

Closes #217

Still to address:

Only the system hoppings have a custom width calculation applied, should also apply the same logic to the leads.
Right now we don't eliminate extremely short hoppings, instead I should use the same logic as in other similar places.
It is extremely hard for the user to reproduce the same behavior without digging into the internals. This is because it is now hard for the user to compute the shortest hopping length.
