Subject: bug#73384: [PATCH] Draw coloured stipples on NS
Date: Sat, 04 Jan 2025 09:49:37 +0100

Many thanks for your comments Alan.  Since I'm only the messenger here,
I'm kindly asking Ben if he can incorporate your comments and post a new
patch.

Reg. your question:

I don't think so, the patch just worked for me.

Best, Arash
