[pve-devel] [PATCH widget-toolkit] fix #6312: limit consent window to viewport size

[Dominik Csapak]

The consent window will try to size itself according to the max/min
constraints set, but those might be too large for some viewport sizes.

Since it's not possible to set those to relative viewport sizes (ExtJS
does it's own layout, so we can't use CSS), we have to save the original
size (while factoring in the constraints) and on resize of the viewport
(or the window) limit ourselves to that (minus 10 px safety margin).

Even with that the window will adhere to the set constraint sizes,
but it should be viewable with any sensible display/viewport size.

we could think about implementing such a limit for all of our windows
in e.g. Toolkit.js, but I'm not sure if that's wise, since not all
windows are as flexible with the size as the consent window.
