From earlier discussion, some important considerations are:

• We don't want full SVG support. There is too much in the spec that is expensive, heavyweight, and/or duplicates what we already have in Flutter.
• We should emphasize in our supported format those operations are effective/efficient/optimized in our graphics engine (Skia).
• We may want to process the format at build time rather than support a full run-time interpreter.
