PresentationLabels

The construct adapter of the anchored labels (field-presentation §FVL-3, matrix FVW-59): it turns the markers of each item, and the true maximum of a robust legend, into anchors. It draws nothing.

In the namespace construct::rendering. Declared in src/libs/libconstruct/construct/rendering/PresentationLabels.hpp.

Detailed description

A marker set builds on the pool the first time an item asks for it, and again when its field, its choices, its mesh or its cut change. Until it lands the item has no anchors, and changed() says when it lands. On a deformed item each anchor moves with its place: the same scale and phase as the vertex shader (§FVG-3).
