Enum Draw 

pub enum Draw {
    Fill(BezPath, Paint),
    Stroke(BezPath, f32, Color),
    Glyphs(FontData, f32, Color, Vec<i16>, Vec<Glyph>),

One drawing command, in scene pixels: what both vello backends replay. Every decision about the drawing is made before a command is made; a backend only translates it into its library’s call.

Variants

Fill(BezPath, Paint)

Stroke(BezPath, f32, Color)

Glyphs(FontData, f32, Color, Vec<i16>, Vec<Glyph>)

A glyph run: its font, size and color, its point on the font’s variation axes — empty for a static font — and its glyphs.

PushClip(BezPath)

PushOpacity(f32, Option<BezPath>)

A layer drawn at an opacity, cut to the path — or to the whole drawing.

PushAdd(BezPath)

A layer added to what is under it, color and alpha alike, so two fills in such layers that meet edge to edge sum to exactly what is in them, with no seam where an edge pixel is partly each. Nothing in it reaches the path, which bounds it.
