Use the system GTK icon set for Pinta icons

[isf63]

Description
Some versions ago, Pinta used a colorful custom iconset for its icons. This can be seen in the screenshot here: https://en.wikipedia.org/wiki/Pinta_(software) Since, the developers have switched to system-supplied icons, but only in B&W.

I personally find the B&W/symbolic icons hard to search through. It would be great if Pinta used the icon theme set in the GTK configuration.

To clarify this Pinta does use the system's GTK icon theme (along with a lot of custom icons, which can be overridden by a theme), but it uses the symbolic icon variants.

I'd be okay with a pull request to add some option to have Pinta use non-symbolic icons. There are a lot of custom icons, though (https://github.com/PintaProject/Pinta/tree/master/Pinta.Resources/icons/hicolor/scalable) which would need non-symbolic variants. Ideally they'd be svg icons to better support different display resolutions, but the old .png icons could maybe be resurrected as a fallback

Eh?
There are no icons at all for me.

I'm not sure what you mean by that .. could you provide some more info please? E.g. are no icons appearing in the UI for you?

Oh ok, it was the icon menus that you're referring to? That's a bit separate from this issue, which is just for the use of coloured icons in the toolbars etc

This issue wasn't obviously pointing at a certain type of icons, so I had assumed that it was related. My bad.

[cameronwhite]

No problem! Just wanted to make sure I understood what you meant with the missing icons

This might be relate to my discussion. I learned from release notes of 2.1.1 that the team has

Updated icons to symbolic SVG icons, which are more usable for dark themes and high-res screens

I'd like to have an option to customize the icon set because me too have some difficulties to distinguish the b/w icons.
