Make borders prettier

[elinorbgr]

This plain gray is quite ugly.

It'd be hardcore to make them "native" (though it does not really means a lot on linux: what's "native" ? GTK ? Qt ? Plain ugly X ?), but at least they could be more pleasant on the eyes.

(This actually require very few wayland knowledge, if anyone feels like designing less ugly borders. I can mentor on any specificities of the crate)

Maybe the KDE Server Decoration Protocol would help out here?

[elinorbgr]

It would help on KDE or compositors implementing this protocol, yes. And supporting it is definitely something I want to do. Though I'm currently in a "wait & see" stage, as there are currently discussions about its potential inclusion in wayland-protocols

Nonetheless, for compositors that require clients to draw their borders in all cases like Gnome, it'd be good to draw borders that are no too ugly.

Closing in favor of Smithay/client-toolkit#1, as this library is to be replaced by Smithay's Client Toolkit.
