[Seaside] JSScript objects have a canvas. Can I somehow use this canvas to put escaped html in my js?

I think this won't work anyway because the canvas is for an old render
context. In fact, we've been talking about refactoring so that the JSObjects
only hold a render context or something instead of the canvas but it's
unclear if that will happen in this release cycle (I suspect not).

I think you ought to be able to use a Builder to get a canvas to use here.
It can then give you back a string. I think it's mostly geared around
passing whole components into it but you can probably get at the canvas and
pass it somewhere... look for sender of #builder and see if you can work it

If not, I'm sure Lukas will have a much better solution for you tomorrow
anyway. ;)
