Byte offset between the start of two consecutive scanlines.
This value is permitted to be negative, denoting a bitmap
whose content is flipped at the x axis.
Byte offset between the start of two consecutive planes.
This value is permitted to be negative. If this value is zero,
the bitmap is assumed to be in chunky format, otherwise it is
assumed to be planar. The difference between chunky and
planar layout lies in the way how color channels are
interleaved. For a chunky format, all channel data for a
single pixel lies consecutively in memory. For a planar
layout, the first channel of all pixel is stored consecutive,
followed by the second channel, and so forth.
