i_pitch is the byte size of a scan line within the plane.

Visible pitch is a hysterical raisin that is supposed to be pixel_pitch 
multiplied by visible width. It may be smaller than pitch due to padding and/
or cropping. If you need to know the visible width, preferrably use 
format.i_visible_width.
