# How it works:
# 1a: DW, DH*dar/DAR - fit to display width
# 1b: DH*DAR/dar, DH - fit to display height
# 1: the min of 1a and 1b these (i.e. fit inside both width and height); for zoomed in view, use the max
# 2a: in_w, in_h*SAR/sar - fit to original width
# 2b: in_w*sar/SAR, in_h - fit to original height
# 2: the max of 2a and 2b (i.e. avoid enlarging both dimensions - let HW scaling handle this)
# output: the min of 1 and 2 (i.e. fulfill both constraints)
# setsar=1 to prevent scaling on the device (skip this if the device actually wants the proper sar to be specified for not performing needless scaling)
