video/out/win_state: don't allow apply_autofit to return 0

Dudemanguy · Dudemanguy · commit 9214b44a6875 · 2026-03-30T00:53:18.000Z
There's no way this coordinate can ever work so don't force callers to
waste time checking for it, so just MPMAX at 1. Fixes a crash in certain
cases if you do --autofit=1x1.
