"""Quick Edit can select every layer (Photoshop Layer ▸ Select All Layers).

Photoshop's Layer ▸ Select ▸ All Layers multi-selects the whole layer stack. The
command box previously had no handling for it, so "select all layers" fell into
the pixel-marquee branch and ran a document selection instead. It now routes to
the same button the Layer menu uses, before the pixel "select all" block.
