This changes the constraints demo so that it fills the window and is a bit more likely the sample code for eframe. It is kind of janky though when I run it, but it seemed janky before I updated things as well.

The eframe update is unfortunate – previously, the egui demo was constrained to a specific canvas, so it could be embedded into a large webpage (mostly written in normal HTML). The idea here is that I could embed multiple small demos into a blog post; I'd like to keep this property.

(eframe upstream hasn't emphasized this use case, so it's not surprising that they've broken it by accident)

I'd rather leave the eframe dependency as-is, since I don't have time to dig into the internals and figure out what changed. Updating image and notify seems fine to me!

If that's important, then I'll look into that.

The updates go well together since they get rid of a few duplicated dependencies, especially on Windows where it gets rid of a whole version of one of the Windows binding crates.

Okay, fixed it and will be updating shortly.

[waywardmonkeys]

Your use case was one that they specifically fixed / improved in eframe 0.28!

Maybe the last update is better!

Looks good! I restored the outer div to make sure it worked and found that we could minimize the CSS somewhat.
