sensor's pixel array.

<entry>The native size of the device, e.g. a sensor's
pixel array. <structfield>left</structfield> and
<structfield>top</structfield> fields are zero for this
target. Setting the native size will generally only make
sense for memory to memory devices where the software can
create a canvas of a given size in which for example a
video frame can be composed. In that case
V4L2_SEL_TGT_NATIVE_SIZE can be used to configure the size
of that canvas.
