+ <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.
