 <p>Pixel step iterators are used to provide iteration over non-adjacent pixels. Common use is a vertical traversal, where the step is the row stride.</p>
 <p>Another application is as a sub-channel view. For example, a red intensity image over interleaved RGB data would use a step iterator adaptor with step sizeof(channel_t)*3 In the latter example the step size could be fixed at compile time for efficiency. Compile-time fixed step can be implemented by providing a step function object that takes the step as a template </p>
