31 * Author: Thomas E. Dickey
33 * A little more interesting than "dots", read a simple image into memory and
34 * measure the time taken to paint it normally vs randomly.
36 * TODO improve use of rgb-names using tsearch.
38 * TODO add option to dump picture in non-optimized mode, e.g., like tput.
39 * TODO write cells/second to stderr (or log)
40 * TODO write picture left-to-right/top-to-bottom
41 * TODO write picture randomly
42 * TODO add one-shot option vs repeat-count before exiting
43 * TODO add option "-xc" for init_color vs init_extended_color
44 * TODO add option "-xa" for init_pair vs alloc_pair
45 * TODO use pad to allow pictures larger than screen
46 * TODO add option to just use convert (which can scale) vs builtin xbm/xpm.
47 * TODO add scr_dump and scr_restore calls
48 * TODO add option for assume_default_colors
