Is it possiable using [png](https://lib.rs/crates/png) for decode emoji png? #48

I am having an issue using swash with WebRender glyph rasterizer. The swash-demo works just fine. So I guess it's that webrender using different gl shader when rendering font glyphs.

Without any changes to swash this is output of emojis using wr_glyph_rasterizer

Agreed on this count. swash shouldn't try to re-invent the wheel.
