Start to use svg instead of png

[vogella]

Description

As of the Eclipse 2025-06 release the platform supports the direct usage of svg files. These icons scale better with the screen resulution.

Would it be an option for EGit to start using svg files directly (this would increase the minimum Eclipse release which can be used)?

Background: https://github.com/eclipse-platform/ui-best-practices/ works on providing a new set of svg icons and was to replace existing svg files. If EGit would use svg files, the new icons could also be used to update Egit.

Example of running Eclipse with replaced icons based on the bash script from eclipse-platform/ui-best-practices#290

Motivation

usage of SVG would scale better and would allow icon replacement in the future.

+1 for migrating EGit to svg icons. I think we already use svg icons as source for all icons (mostly in png format) which are located here

This would push EGit to Eclipse 2025-06. Is that fine?

I think that's ok.

Push change without increasing the minimum requirements, as I don't know how to do this. https://eclipse.gerrithub.io/c/eclipse-egit/egit/+/1231933

Note: Pushing to Gerrit does not work for me (No Permisssion), i have always to push via the command line:

actually the oldest version supported by EGit is already 2025-06, that means this change doesn't affect which IDE versions we support

Nightly again not updated AFAICS.

Switched to local builds, the nightly seems to be unreliable.

It seems the EGit CI became much slower somewhen last week, the last 3 EGit builds were aborted after the configured job timeout of 80min. Before these builds usually took around 30min.

I filed an issue https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/7229 and it seems there are some infrastructure issues with the CI
