Border not properly aligned with underlying container #554

I noticed while working on cosmic-osd/#54 and playing around with the border thickness, that the edge of a container is not always well-aligned with its border. Especially the rounded edge of a container is not aligned with the inner edge of the border. I cranked up the border width to exaggerate this effect:

This is not only an issue when exaggerated like this. It is also noticeable with display scaling turned up on the applets. Excuse the analog screenshot; screenshots with scaling were blurry for some reason. Again, notice how the background is bleeding through the rounded corners, and even on the straight edges.

The issue in the first image (fixed with iced/018051e) was related to an incorrect calculation in tiny-skia. I am also not noticing the issue in the second screenshot with wgpu.
