Every 1.12 map addon places its art in absolute pixels against
WorldMapDetailFrame's 1002x668 — pfUI's reveal does it one SetPoint per
tile — so that size is a contract, not a size. 1.12's windowed mode puts
WORLDMAP_WINDOWED_SCALE (0.7) on the frame and on WorldMapButton; under
the canvas the container already carries the window, so that scale was a
second authority on the same rect and, with the frame SetAllPoints to the
canvas, came back as unit size: 1002 / 0.7 = 1431. Everything absolute
inside it landed at 0.700 of where it belonged, which is grom's
screenshot drawing Coldridge Valley twice, and the mouse surface kept its
XML 1002x668 beside 1431 units of art, so clicks read 70% of the map.
SeatOnCanvas makes the canvas the only authority: both frames to scale 1,
the frame filling the canvas, the button given the art's rect — explicitly
sized, because pfUI reads WorldMapButton:GetSize() to size the whole map
window. Re-run after Minimize/Maximize and on every canvas resize.
Rescaling the children this file knows the names of could never have
fixed it; the children it does not know the names of are the point.
saved-variables.lua now goes through saved_home, so a capture with
$WOW_CAPTURE_SAVED opens the player's windowed map — the only mode the
bug exists in, and the reason neither harness had ever seen it.
