+Notes:
+MSW = the maximal width allowed for a stripe
+ i.MX31: 720, i.MX35: 800, i.MX37/51/53: 1024
+cirr = the maximal inverse resizing ratio for which overlap in the input
+ is requested; typically cirr~2
+equal_stripes:
+ 0: each stripe is allowed to have independent parameters
+ for maximal image quality
+ 1: the stripes are requested to have identical parameters
+ (except the base address), for maximal performance
+If performance is the top priority (above image quality)
+ Avoid overlap, by setting CIRR = 0
+ This will also force effectively identical_stripes = 1
+ Choose IF & OF that corresponds to the same IOX/SX for both stripes
+ Choose IFW & OFW such that
+ IFW/IM, IFW/IF, OFW/OM, OFW/OF are even integers
+ The function returns an error status:
+ 0: no error
+ 1: invalid input parameters -> aborted without result
+ Valid parameters should satisfy the following conditions
+ IFW <= OFW, otherwise downsizing is required
+ - which is not supported yet
+ 4 <= IFW,OFW, so some interpolation may be needed even without overlap
+ IM, OM, IF, OF should not vanish
+ 2*IF <= IFW
+ so the frame can be split to two equal stripes, even without overlap
+ 2*(OF+IF/irr_opt) <= OFW
+ so a valid positive INW exists even for equal stripes
+ OF <= MSW, otherwise, the left stripe cannot be sufficiently large
+ MSW < OFW, so splitting to stripes is required
+ OFW <= 2*MSW, so two stripes are sufficient
+ (this also implies that 2<=MSW)
+ 2: OF is not a multiple of OM - not fully-supported yet
+ Output is produced but OW is not guaranited to be a multiple of OM
+ 4: OFW reduced to be a multiple of OM
+ 8: CIRR > 1: truncated to 1
+ Overlap is not supported (and not needed) y for upsizing)
