have some good defaults for g-overlay

[sjmiles]

I haven't thought about this much, so this may be wrong-headed, but my knee-jerk reaction is that the usage shown by the overlay.html workbench file is too complicated.

It would be nice if g-overlay had some defaults such that when declared simply it produces pleasing output.

I don't mean that the workbench file (overlay.html) should be trivial, because that goes against how we have defined files in that folder, but I would like to be able to make a trivial usage that still looks good.

We may be bumping up against theming issues here.

Yes, agree. Will make that happen. One current limitation is the inability to put animation keyframes into a scoped stylesheet (wkb.ug/93545).

Ok. I'm not averse to requiring an external stylesheet as a stopgap for that problem.
