Fix color

A follow up to support COLRv1.

# Note: it seems Noto Color Emoji has many variants. Only that of COLRv1 format
# is supported, so this might not work on installed font of Noto Color Emoji.

Note to self: since paint() is invoked AFTER outline_glyph(), it cannot be treated as an attribute of lyon::path::Path::builder_with_attributes(). Record the color of the layer here and use it afterwards.
