Compute the max pixel step for each plane of an image with a
format described by pixdesc.
The pixel step is the distance in bytes between the first byte of
the group of bytes which describe a pixel component and the first
byte of the successive group in the same plane for the same
component.
@param max_pixsteps an array which is filled with the max pixel step
for each plane. Since a plane may contain different pixel
components, the computed max_pixstepsplane is relative to the
component in the plane with the max pixel step.
@param max_pixstep_comps an array which is filled with the component
for each plane which has the max pixel step. May be NULL.
