Failed to create screenshot on Pinta/Windows

[grofaty]

Latest Pinta 2.2-dev from master repository on Windows 10: https://github.com/PintaProject/Pinta/actions/runs/7378423225/artifacts/1141941547

1. Hamburger menu | File | New Screnshoot and error appears: "Failed to take screenshot". See attachment.

Additional test:
I have tested on Pinta 2-2-dev on master on Ubuntu 23.10 and screenshot works fine. It looks like Windows specific problem.

Ah yes, this still needs to be re-implemented for Windows in the GTK4 builds.
GTK4 removed the APIs we used to use for taking screenshots, so we now need to hook into something platform-specific which we can launch and then bring the screenshot back into Pinta (on Linux this is the screenshot portal, and on macOS the system screen capture utility)

[Cameron White (cameronwhite91)]

I'm putting this on the 2.2 milestone for now so I remember to do some investigation of this (now that we actually have a working GTK4 build on Windows). But I'm probably okay with bumping this to 2.3 since it's not too hard to use another application to take a screenshot first

What I like about Pinta's snapshot is some, set time to e.g. 5 seconds, move to some other program, open some menus etc and snapshot is automatically performed. Snapshot tools sometimes closes down some menu options etc. when Print-Screen key is pressed.

BTW, I remember screenshot used to also record mouse icons, but it doesn't anymore in Pinta 2.2-dev on Linux and also not on Pinta 2.1.1-flatpak. This is separate issue.

I am fine this feature is postponed to 2.3, if it is show stopper.
