Visualising wholes and parts

It'd be nice to have an option to visualise event fragments with pianoroll/punchcard etc.

Currently wholes are visualised, rather than parts: https://strudel.cc/#cygiYmQiKS5tYXNrKCIxIH4iKS5wdW5jaGNhcmQoKQ%3D%3D

and parts without onsets are sometimes-but-not-always ignored: https://strudel.cc/#cygiYmQiKS5tYXNrKCJ%2BIDEiKS5wdW5jaGNhcmQoKQ%3D%3D

Events with missing offsets could look like this:

Or with the 'whole' shown:

Events with missing onsets could be greyed out, to show that they normally don't have any effect:
