What does @svg do in VR?

[tbp1...@gmail.com]

@ekr recently fielded a PR for "VR plugin crashes for @svg nodes (Qt6 only) #2134".  I sanitized VR3 for this situation myself not long ago.  The thing is, what is supposed to happen for an @svg node anyway?  The VR3 code, which was taken from VR, doesn't seem to work even with QT5.  And if you feed a node whose body starts with <svg> to a browser or browser panel (e.g., WebEngineView), the svg will be displayed as intended.

So what is an @svg node supposed to give us that is different from this?  Perhaps it's not actually needed any more?

My apologies for the delay in responding.

The body of an @svg can contain either:

1. The xml text of an svg image, containing an <svg> element, or

2. The absolute path to an svg file.

Thank you.  I'll get VR3 to act this way.  Either way, there is no need any more for the QSvgWidget so far as I can see.  The WebEngineView browser widget will display the svg.

Provided it exists :-)

I'm thinking PyQt6 will get a QWebengineView before it gets a QSvgWidget...
