Errors from old rust dependencies

[pallaswept]

I noticed my STL thumbnails are not working any more today. I followed a chain of error messages about the various crashes and updated stl-thumb from 0.5.0 to the head of master (adding the new freetype dep) and after this, it would function in CLI, but in Dolphin, generate errors, and only one thumbnail at a time:

Feb 20 14:59:02 Pallas dolphin[80095]: thread '<unnamed>' panicked at /home/abuild/rpmbuild/BUILD/stl-thumb-0.5.0_50-build/stl-thumb-0.5.0~50/vendor/winit-0.27.5/src/event_loop.rs:106:13:
Feb 20 14:59:02 Pallas dolphin[80095]: Creating EventLoop multiple times is not supported.

And that is mentioned on their github repo as being fixed now in recent versions.

I'm afraid I don't have much time to spend on this right now and I'm a rust idiot anyway so this report is a bit light on detail, but I wanted to give you some hopefully useful info. Let me know if you need any details.
