ICLIO_API void icl::io::labelImage ( core::ImgBase *  image,
const std::string &  label 

draws a label into the upper left image corner

This utility function can be used e.g. to identify images in longer computation queues. Internally is uses a static map of hard-coded ascii-art letters ('a'-'z)'=('A'-'Z'), ('0'-'9') and ' '-'/' are defined yet. which associates letters to letter images and corresponding offsets. Some tests showed, that is runs very fast (about 100ns per call). Note, that no line-break mechanism is implemented, so the labeling is restricted to a single line, which is cropped, if the label would overlap with the right or bottom image border.
