Enum CoordinateSpace 

#[repr(C)]
pub enum CoordinateSpace {
    Window = 0,
    ScrollFrame = 1,
    Parent = 2,
    ReferenceFrame = 3,
}

Marker enum documenting which coordinate space a geometric value is in.

This is for documentation and debugging purposes only — it does not enforce type safety at compile time. Use comments like [CoordinateSpace::Window] or [CoordinateSpace::ScrollFrame] in code to document coordinate contexts.

Common bug pattern: passing Window-space coordinates where ScrollFrame-space is expected (or vice versa). The scroll frame creates a new spatial node, so primitives must be offset by the frame origin.

Variants

Window = 0

Absolute coordinates from window top-left (0,0). Layout engine output is in this space.

ScrollFrame = 1

Relative to scroll frame content origin. Transformation: scroll_pos = window_pos - scroll_frame_origin

Parent = 2

Relative to parent node’s content box origin.

ReferenceFrame = 3

Relative to a CSS transform reference frame origin.
