Log Message:
syncdoom: anchor the sixel image at top-left when terminal pixels are unknown

Sixel is positioned by text cell, but the image is sized in pixels; on a terminal
that doesn't report its real cell-pixel size (e.g. xterm with allowWindowOps off)
the door assumed 16px-tall cells, so the "centered" row landed too low and the
frame looked bottom-anchored. When real geometry is unknown, anchor the sixel at
row 1, col 1 -- predictable, and what a user expects. JXL/PPM (SyncTERM, real
geometry) still center via the APC DX/DY offsets.
