I recently realized that WebRender has a hard C dependencies (freetype2/harfbuzz), while we'd prefer font stack using Rust(fontdb/ttf_parser/rustybuzz/fontdue/swash etc). I've experimenting with replacing WebRender wr_glyph_rasterizer with [fontdue](https://github.com/mooman219/fontdue). It turns out...

png/svg fonts is working using patched [`wr_glyph_rasterizer`](https://github.com/declantsien/webrender/tree/fontdue).

Also resizing the emoji pngs is not necessary in my case. wr_glyph_rasterizer just need to know the scale of the [Image](https://docs.rs/swash/latest/swash/scale/image/struct.Image.html)

I assume we can build the tokens from str. let `char_indices` compute the offset here. ``` let source = "AB🙃"; source.char_indices().map(|(i, ch)| Token { ch, offset: i as u32, len:...
