Subject: 30.0.50; alpha-background doesn't effect background of stipple in
 emacs 30.0.50 pgtk
Date: Thu, 03 Aug 2023 18:07:21 +0200

The background of stipple stays opaque with alpha-background parameter
set for transparency.
This came up in the use of the new package 'indent-bars'.
The github issue: https://github.com/jdtsmith/indent-bars/issues/8
I tested this with 'emacs -Q' only enabling the needed packages (compat
and indent-bars).
