Important traits for RowIterator<P>

impl<P: Iterator<Item = Pixel<Rgb565>>> Iterator for RowIterator<P> type Item = PixelRow;

fn to_rows<P>(pixels: P) -> RowIterator<P> where
    P: Iterator<Item = Pixel<Rgb565>>, 

Batch the pixels into Pixel Rows, which are contiguous pixels on the same row. P can be any Pixel Iterator (e.g. a rectangle).
