Subwindow translucency flag is forceful, this probably shouldn't impact anything since it only changes things on compositor level. Alternatively could be done individually for each child window. Unfortunately flag needs to be set before the window is shown (even if it was shown attached), so dynamically tweaking it doesn't seem to work. Overall flag change shouldn't introduce any significant performance drawbacks, if it does converting it to a config option is trivial.

This is for demonstration purposes. To see the change in effect, one needs to tweak the theme CSS. To make workspace transparent,
QMdiAreabackground needs to have the desired alpha (e.g.QMdiArea { background: rgba(0,0,0,0); }That will also support background images with translucent elements.Modals are not supported yet (just because they're neither subwindows nor top-level), changes to support them are trivial.

Forcing is done in order to have the proof-of-concept done with a smaller diff.
