* Starting from a provided origin, visit connected pixels using a visitor function.
* After visiting a pixel, select the 4 connected pixels (up, right, down, left).
* Call the provided visitor on each pixel. The visitor should return true if the
* pixel should be considered as connected. If the pixel is connected repeat the
* process with its own connected pixels
*
* TODO : Julian : The visitor is also responsible for making sure a pixel is never
* visited twice. This could be handled by default by this method.
*
* @return {Array} the array of visited pixels {col, row}
