disable clipboard watermarks

Issue migrated from trac ticket # 2634

component: clipboard | priority: minor | resolution: wontfix

When I copy an image to or from the clipboard using xpra, it has a one-line timestamp watermark that says:

via Xpra, 2020-03-11T19:09:21.131581

This was my local time (EDT) and was 12 seconds after the screen shot was made, probably referring to when Xpra copied it to my local system.

I would like this to be disabled by default (unless debug is on).

I can't find this with a quick search within the source code, nor can I find any references to this online except perhaps for the Xpra News summary for 3.0 Important Features (2019-09-20), which mentions:\\

Clipboard:

• HTML5 support for copying images: #2312 (with watermarking)

\I'm using Debian Testing, xpra 3.0.6+dfsg1-1, on both sides.

To disable the watermark, use:

XPRA_CLIPBOARD_IMAGE_STAMP=0 xpra ...

or

xpra --env=XPRA_CLIPBOARD_IMAGE_STAMP=0 ...

The default will not be changed for now.

(changing title: this has nothing to do with screenshots)

Ah ha! I hadn't searched for the word "stamp" when I was looking for this.

I'll have to use a wrapper to ensure that variable is set when I invoke xpra.

Perhaps others with this issue who search for "watermark" will find this closed ticket. I recommend updating your documentation too, perhaps at [[Clipboard]].

Thanks for your hard work on this project.
