// Explanation:
// We use the gdal histogram creation routine is called for each selected
// layer. Currently the hist is hardcoded
// to create 256 bins. Each bin stores the total number of cells that
// fit into the range defined by that bin.
//
// The graph routine below determines the greatest number of pixesl in any given
// The graph routine below determines the greatest number of pixels in any given
// bin in all selected layers, and the min. It then draws a scaled line between min
// and max - scaled to image height. 1 line drawn per selected band
