SVG Native Spec

Is your feature request related to a problem? Please describe.

Adobe & Apple are developing a SVG Native subset of SVG. In addition, there appears to be a private SVG library on iOS. Putting these two together, you might conclude Apple may eventually support SVG Native images in iOS without a webview. In addition, Adobe already has a SVG Native renderer for iOS

It would be great if the SVG output also conformed to this subset. It looks like it's already mostly compliant. Currently I can see the following issues:

• Use of svg inside the main svg [1], [2], [3]
• em units - I can't quite work out where these are used, but I do remember seeing them
• Text - I think this is just a fallback - maybe just a way to turn this off and throw an exception would suffice

And I noticed these too - but not certain they would actually show up if someone was to make an iOS library

• foreignObject

Start with ts/output/svg/Wrappers/mo.ts, then inspect how the SVG output handles nested svg elements, em units, text, and foreignObject. Compare representative generated output with the SVG Native subset specification; done means the relevant output conforms to the subset or the unsupported cases have an explicit, verified handling.
