Canvas redraw: review follow-ups to the strengthened tests
- A 3D effect that builds nothing: af754bcb2 said the object draws exactly
as without it under a Drop Shadow or Gaussian Blur. That holds only for
a stroked object. With only a fill, the raster effect draws from the
art made for the object, where without the 3D effect it is clipped to
the path, so Roughen's spikes differ: the earlier wording was right.
The test keeps the stroked cases exact and restores fill-only cases
with a Drop Shadow and a Gaussian Blur, which differ in under 4% of
the pixels and nowhere inside the path. Its reach check compares with
the object drawn without its raster effect, since Roughen alone
reaches past the path.
- The Vector Halftone test's bounds are a consistency check, and only
holding no art tests the branch: its doc no longer says no solid is
built (the free measure's halftone arm builds one). The overprint
test's area check is labeled likewise.
- Recoloring a traced shape bounds the area the renderer that drew the
trace object measures too, inflated by half the stroke and a pixel.
- The let-go test pins the nothing-to-draw branch: no frame, whole or
part, began since the measure.
- The parity doc's feature row names the stack overflow fix and its
test; a group test's doc says what its fixture holds.
