I have to object:  The idea was first introduced in the Mac version of a
POV-Ray 3.1 beta about three and a half years ago.

At the time it was "stolen" from a not less historic Macintosh application
that existed long before there even was a usable WinDOS or an established
and accepted X based GUI - Photoshop.
