New macOS art provider not providing art that scales (Issue #26317)
Daniel Kulp
dkulp created an issue (wxWidgets/wxWidgets#26317)Description
The new art provider that is using the SF symbols for the various art things on macOS is not producing BitmapBundles that will actually scale the art depending on requested size. This is easily shown in the artprov sample.

As above... SOME of the art (stuff that doesn't come from the symbols) does scale, but looks bad:

Since the Art provider provides a wxBitmapBundle that SHOULD be able to produce bitmaps of any requested size, I'd expect the art to scale appropriately. Since the symbols are vector, I'd expect the scaled symbols to look great, particularly on retina displays.
Patch or snippet allowing to reproduce the problem:
Just use the artprov sample.
To Reproduce:
Open artprov sample, open the resource browser from the menu, select various arts.

I'll try to come up with something, the GO_TO_PARENT btw is not from the native art provider but from the default art provider that uses the up.xpm file, so this is different
