Detailed Description

One rectangular lattice of sample points over a rasterisation ROI.

Every shape whose mask is evaluated on a coarse grid and then interpolated back up describes that grid the same way: a cell count, a spacing in output pixels, the ROI origin, and the inverse of the ROI scale. x0/y0 are the index of the first cell – non-zero for the shapes that grid only their own bounding box (circle, ellipse), zero for the ones that grid the whole ROI (gradient).
