Current Limitations:

Currently, a small fraction of SVGs may render as black squares or as being filled completely black
- Such SVGs contain properties not supported by the Direct2D API which this extension uses
- There is also no support for text glyphs
Overall, a vast majority of SVGs should render correctly. If you notice any from a particular program that consistently don't render, you can create an issue and I can see if anything can be done.
