Detailed Description

SubRunData represents an AtlasSubRun subspan for which per-pixel coverage data comes from a persistent glyph atlas texture.

The bounds() represent the bounds of the entire AtlasSubRun and does not directly map to the local coordinates of this particular subspan. Rather, the dimensions and offset coordinates of a subspan are defined in a coordinate space that is partially transformed by a decomposition of the local-to-device matrix computed by the AtlasSubRun per instance. The transform of the draw is the rest of the decomposed transform (often only a translation) that maps this intermediate space to the device-space coordinates of the draw.

The local coordinates used in shading are derived by transforming the final device coordinates using the inverse of the local-to-device matrix.
