Review of #1693 found that cast_effects built the picture content that a shadow,
a glow and a reflection are drawn from without converting a tiled fill to
points, so inside a scaled group the reflection of a tiled picture showed
child-space tiles while its face showed the right ones.
The content now goes through paint::tiled_picture_per_point with per_point_xy,
as the face does.
Test: a tiled picture's reflection in groups scaled 0.25, 1600 and 2x0.5 shows
the same colours as in an unscaled group; it fails without the change.

Review of #1693 found two more places that drew a tiled picture fill in the
shape's own (child-space) units inside a scaled group.
A group nested in a scaled group stored its own tiled fill unconverted, so the
members that take it (grpFill) got oversized tiles. The owning group now
converts the fill with per_point_xy when it stores it, so inheriting members,
directly or through a chain of grpFill groups, get the converted tile.
A picture shape (p:pic) whose blip fill is a tile passed its own fill straight
to paint::picture. It now goes through paint::tiled_picture_per_point, which
tiled_per_point also uses.
Tests: a group's tile passed to its members and a picture shape's own tile, each
in outer groups scaled 1, 0.25, 1600 and 2x0.5; both fail without the change.
Docs: the Picture and texture fill checklist row is re-assessed (remains P) with
its status line and revision history, and the ROADMAP progress log row mentions
both cases.

A tiled picture fill (a:blipFill with a:tile) was sized in the shape's own
units. Inside a group whose child space differs from its box (old decks write
child spaces ~1800 times smaller) one tile covered hundreds of boxes, so the
fill showed a single flat texel instead of the texture.
PowerPoint's own PNG export of a synthetic probe deck shows the tile keeps its
size, offset, anchor and mirroring in slide points whatever the group's scale,
uniform or stretched unevenly, nested or flipped. The tile is now converted
from points to shape units per axis (Renderer::per_point_xy, paint::
tiled_per_point), and snapped to whole device pixels per axis.
Tiles with rotWithShape="0" are drawn in device pixels and were sized in
pixels, ignoring the zoom (even outside groups); they are now sized to pixels
first.
Tests: a tile in groups of seven scales (uniform and uneven, wide and tall
tile), and an upright tile in a turned shape at zoom 1 and 2.

effects_below merged all subpaths into one silhouette and filled it
with the NonZero rule, discarding each subpath's even_odd flag, so the
holes of donut, frame and similar preset shapes filled in under outer
shadows, glows and reflections. Fill each participating subpath under
its own fill rule at the three effect fill sites, mirroring
fill_geometry; the glow stroke keeps the merged silhouette.
Fixes#1596. The picture-content shadow clip path is unchanged
(that is #1597's territory).
An ellipse at the EMU limit, compounding group scales or custom-geometry
guides could reach vello's flattener with an outline billions of pixels
long; it sizes its buffer by that length and the allocation aborts the
process. geometry::drawable() rejects a shape with a non-finite path
point, then measures the outline's control box (which always holds the
curve, unlike the tight bounding box when its extremum overflows) unioned
with the frame; past 1e7 device pixels the shape is skipped with a warning.
Rebased onto the render module split: the guard now lives in geometry.rs
and renderer.rs.
