Skia renderer

[bjornharrtell]

Rationale:

• Likely (much?) better performance
• Well supported

Notes:

• Requires C++ 17 as minimum
• Currently working against local Skia compiled with bin/gn gen out/Static --args='is_official_build=true cc="clang" cxx="clang++" skia_pdf_subset_harfbuzz=false skia_use_libwebp_decode=false skia_use_libwebp_encode=false skia_use_gl=false' is_debug=false

Well this is an interesting addition. Are there advantages over AGG?

[bjornharrtell]

@sdlime I have reason to believe Skia can significantly outperform AGG.

[bjornharrtell]

When I began on this I didn't know if it would be achievable without too much effort.. but it is now capable of producing:

So I'm motivated to continue. :)

Did some early benchmarking on 3+ million polygon squares. AGG is a lot faster on that case... somewhere 50% - 80% faster. I believe I've compiled Skia with the optimal settings so currently I can't explain this other than that Skia isn't as fast as I had assumed/thought.

Still seems like an interesting option as it is maintained and under active development.

@bjornharrtell I'll do some Windows testing on this this week. I agree with Steve here, the benefits of using a library that is so well maintained can outweigh other limitations.

@pelord , could you clarify what you want to say?

removing the 8.2.0 milestone label due to recent discussion.
