Struct EngineDraw 

pub struct EngineDraw {
    pub paint: Paint,
    pub depth: u32,
    pub strip_range: Range<usize>,
}

One recorded draw: a paint, a depth, and the strips it covers.

paint is a vello_common Paint — either an inline solid colour or an index into the frame’s encoded-paint table. Carrying the vello type here (rather than a peniko::Brush) is what keeps the GPU-side conversion a plain field read, and is the seam the paint-encoding pass writes into.

Fields

paint: Paint

Paint applied to every strip in strip_range.

depth: u32

Painter’s-algorithm depth, assigned by DepthCounter.

The back-most draw of a frame is 0 and each subsequent draw is one greater, matching the GPU strip instance’s depth_index contract: a larger value is nearer the viewer and wins the depth test.

strip_range: Range<usize>

Half-open range selecting this draw’s strips from the frame’s shared strip storage.
