[nfwyst]

it is too wide when the file name is long, so i'd like to limit the width when in adaptive_size mode

We could repurpose view.width to have it apply when using adaptive size. This will need further investigation.

A new view.max_width option with the same types as view.width is a pragmatic solution.
