render v0.7.0 draws all four mesh shadings — free-form and lattice-form triangles, Coons and tensor patches — and places a pattern in the space of the form that names it rather than at the page's origin.

Measured on the whole corpus: 120 617 pages drawn each way with no panics, 437 changed, every one of the biggest changes moving towards what macOS's own renderer draws.

An ExtGState luminosity soft mask is the gap that takes the meshes' place in the scope list: it is not applied, so a figure that fades a surface comes out at full strength. Constant alpha is honoured.
