Lack of borders around menus, widgets, windows, panels, etc.

[Grant Edwards <grant b edwards gmail com>]

After a recent upgrade (probably from 1.x to 3.x) I noticed that there
are now no borders around windows/panels, popup/dropdown menus,
scrollbars, etc.

For examples, see

At first I thought I would get used to it, but there are still
situations where I find it visually confusing.

Is there any way to get those borders back?

I particularly miss the left/right-hand borders around the file panes
when looking at code comparisons.

Is there any way to get those borders back?
