Elvis33LE d438f84225 Shape gradients: honour midpoints, opacity stops, offset, dither and align (#1321) ...

vector::Paint::from_fill discarded every gradient field beyond stops,
angle, scale and style, so Photoshop files whose shape fills use opacity
stops, colour midpoints, a centre offset (Ofst), dither or no
"Align with layer" rendered with the wrong ramp, alpha, position or
banding. Paint::Gradient now carries the full ramp (sorted stops,
midpoints, opacity stops, dither) and the compositor's geometry
(centre offset, whole-pixel end-point snapping, pixel-corner sampling,
the align frame choice: shape bounds or canvas), with shape strokes
painting through the same path.

The vector crate cannot depend on compose, so the ramp and geometry
mirror effects::gradient_units/gradient_t, fill_layout::gradient_layout
and gradient_fill::{Ramp, midpoint_remap, dither}. A parity test in
compose (which sees both) renders each non-default field, style and
frame as a shape layer and as a fill layer and requires equal pixels;
from_fill binds every Fill::Gradient field — no ".." — so a new field
fails to compile until the shape renderer honours it.
