* Shapes: a solid fill keeps its transparency A shape's fill colour can carry a:alpha, its opacity. WordCraft dropped it, so a translucent white wash laid over a picture was drawn opaque and hid the picture. The transparency is now read into the shape, drawn on screen and in the PDF, and written back. * Fix #1600 freeform and soft-edge fill opacity * #1600: wrap canonical caret sampler signature * #1600: format canonical integration * #1600: assert canonical DOCX alpha round-trip * #1600: document canonical shape opacity API * Adapt alpha fixture to rectangle render bounds * docs: one file-format-parity row for soft-edge fill opacity, status line --------- Co-authored-by: Brandon Thomas <echelon@gmail.com>
