The GTE squash + stretched present are held off until the game's
entry PC fires (fntrace_is_game_started): the Sony logo, PlayStation
diamond and BIOS shell render exactly as on original 4:3 hardware,
then widescreen engages at game entry. While disengaged the present
path pins to native 4:3 (same path FMV frames use), and the GTE/GPU
squash configure calls are deferred to the engage point so no boot
geometry is squashed.
Starts already-engaged when the configured aspect is 4:3 (nothing to
defer). User-requested.
