  • Tiling patterns
• Use white as background when passing in a fully transparent background colour to devices that doesn't support alpha (notably jpeg) (#91)
• ragg now defers symbol font resolving to systemfonts which makes it possible to register alternative symbol fonts using register_font() (#90)
