* measure the time taken to paint it normally vs randomly.
*
* TODO improve use of rgb-names using tsearch.
- * TODO when not using tsearch, dispense with intermediate index
- * TODO count/report uses of each color, giving percentiles.
*
+ * TODO add option to dump picture in non-optimized mode, e.g., like tput.
* TODO write cells/second to stderr (or log)
* TODO write picture left-to-right/top-to-bottom
* TODO write picture randomly
