[pve-devel] [RFC widget-toolkit] ui: add InfoMultiWidget, to be used for RAM

[Dominik Csapak]

in general i'm not really happy with the manual insertion of a div here,
wouldn't it also be possible to extend the progressbar
and change the rendertemplate?

that way we could have a way nicer interface than
"get the dom element if it exists, and manually set the css classes"

here you have to check if arcsize is set, because if it's
not, the result here is 'NaN' which gets interpreted as width: 0%

i know this was before the dark theme, but this should probably be a css variable?
