/*
Extended Tv, by barberofcivil, http://chdk.setepontos.com/index.php/topic,4392.0.html
Explanation by reyalP:
In every port, the original shutter overrides (as opposed to super long exposure) worked by
setting the propcase values at some point after auto-exposure has happened (except in manual
modes, where the manual control propcases may be used instead). The Canon code previously took
these values unchanged for short exposures. In newer cameras, like on the SX10 / SD980, the value
is changed, apparently some time after it has been retrieved from the propcase. We know this is
the case, because the propcase value itself doesn't get clamped to the allowed range (if it did,
barberofcivil's code wouldn't work).
