OT-SVG support: binding SkGraphics::SetOpenTypeSVGDecoderFactory()

[HinTak]

Is your feature request related to a problem?

The skia-python equivalent is in:

https://github.com/kyamagu/skia-python/blob/e0b030c14e33f70880cfcc502eaeed898a77fc3c/src/skia/main.cpp#L82

Either provide that as a extra /optional call, or put it in SkiaSharp somewhere during load-time, one off, as in skia-python. The line switches on OT-SVG colour font support within skia.

You might need to add a little to your libskiasharp.so process, but ask me if you encounter problems. (I am the one who put that line in skia-python).

And possibly reference this shell script for skia build options:

Describe the solution you would like

Support ot-svg colour fonts

Describe alternatives you have considered

This is an obscure and new part of skia's api (since m103 or thereabouts, I believe), it unlikely you have already bound it yet.

Didn't know you are so behind compared to skia-python - you need the svg module for the functionality I mentioned. The svg module became non-experimental in m88. I.e. you might need to deal with #2689 first.
