Agreed, I’m also -1000 on rendering SVG icons on the fly. I’ve actually tried 
something like this, with some simple icons rendered in Graphiti using Batik. 
It was just way too slow. So we ended up writing some code that rendered the 
icons as PNG during the build process.

I’m not saying it cannot be done. But then I think we need something way more 
powerful than Batik. Also I think some serious work on icon handling is 
required. Adding support for @2x icons took quite a bit of effort. Is it really 
worth it?

Best regards,
