Open and save .ora with pixel layers (any offset), nested groups, pass-through
groups, names, visibility, opacity, edit/alpha locks and blend modes (svg:* plus
Krita's krita:* names), at 8 and 16 bit. Save applies pixel masks, renders
text/shape/fill/smart layers to pixels and reports what OpenRaster can't hold.
Wired into File > Open/Save, the CLI, automation/MCP, the web picker and the
desktop file associations. Checked against 34 Krita 5.2.9-authored files
(opt-in krita_corpus test) and Krita re-opening our exports.
