Re: New breve rest with ledger lines (issue4650052)

[bordage . bertrand]

Updated with the good bounds.

The problem with mensural/neomensural/Petrucci styles is that they often
have different ledger line thicknesses. The best solution is to get
these ledger lines out of metafont. But this requires much more work.

For the moment, the exception is handled by the next "if", line 100.

Thanks!
