Give menus dropshadows

[ninavizz]

The problem you're addressing (if any)
When I open a menu in an app, it typically has an outline—but no dropshadow. This presents a usability problem, with making it difficult to disambiguate what is "in front" vs what is "behind." For reference, I'm on Qubes 4.0.

Describe the solution you'd like
Just a dropshadow.
The mockup below has a .7 alpha #000000 10px dropshadow, w/o any x/y offsets.

Where is the value to a user, and who might that user be?
Sighted users desiring clearer visual hierarchies and focus areas in their UI.

Related, non-duplicate issues
Maybe #6414, but nothing else I was able to see.

This is just what MIcrosft has wrecked in theier design since Windows 8. Lack of a clear separation between fore- and backgroung makes these systems nearly unusable. Qubes is allready far better, and getting still beter with your efforts!

@ninavizz Do you mean something like this to be turned on by default?

[GWeck]

That's it - exactly!

[ninavizz]

YES!! That, as well as the OS menus—but for folks working in apps in qubes, DEFINITELY THAT would be a hyooge "general clarity" usability help to keep brains from cramping! TY! <3

actually this was very easy to do. I have done a pull request to enable it by default but this was an option in xfce.
To enable it in your version, click on the top left corner then go to System Tools --> Window Manager Tweaks --> Compositor and then make sure Show shadows under popup windows is checked.

If you want to do it through command line, open a dom0 terminal and then paste this :

xfconf-query -c xfwm4 -p /general/show_popup_shadow -s true

This uses xfconf-query tool to change the show_popup_shadow to true.

@DemiMarie Was there a reason this hadn't been done before? I seem to remember there being one and am curious, now that this PR has been submitted.

Thank you @p1xxxel!! I will go do that to my own QubesOS machine, now. :D

@ninavizz I am honestly not certain. Personally I was not aware that this option existed.
