ReflectionsShader class final
reflections.frag: screen-space reflections, marched against the surface
buffer.
The part that looked wrong was wrong. This file used to carry a note that
the ray's screen position was ndc.xy * 0.5 + 0.5 with no v flip, where
the shadow lookups flip — transcribed exactly, because a backend does not
get to settle a disagreement between conventions by quietly picking one. It
was a disagreement, and the shadow lookup had the right end of it: the march
read the surface buffer upside down on every backend whose row zero is at
the top, which is Impeller and this one. See UvFromNdc in reflections.frag.
