Description

Hi,

Some applications have "nested windows". E.g. Virtualbox, freerdp/vinagre, vnc etc. In these cases it would be nice if alt+drag behaviour did move the "nested" window.

I propose that xfwm4 gets more settings, to allow, setting some processes as "blacklisted" for the alt+drag behaviour. Then virtualbox/vinagre can be blacklisted to allow passing through the alt+drag events through to the nested child windows.

One implementation of this feature for win32 can be seen at https://stefansundin.github.io/altdrag/ .
