[Canvas] items can be configured with "stippling"
(are there any other occurrences of stippling in Tk?).

What does ''stippling'' mean though?








The small sequence which follows illustrates the appearance of stippling.  The
page on [bitmap]s explains more of their nature.
    set bitmap_list {error gray75 gray50 gray25 gray12 hourglass
        info questhead question warning document stationery edition
        application accessory folder pfolder trash floppy ramdisk
        cdrom preferences querydoc stop note caution}

    set bitmap_list {error gray75 gray50 gray25 gray12 hourglass
        info questhead question warning }


    pack [canvas .c -width 1000 -height 1000 -background skyBlue]
    set i 0
    foreach bitmap $bitmap_list {
        incr i
        set num [expr 80 * $i]
        set num1 [expr $num - 40]
        set num2 [expr $num + 40]
        .c create oval $num1 $num1 $num2 $num2 -fill red -tag $bitmap
        .c itemconfigure $bitmap -stipple $bitmap
    }
    .c create oval 300 40 380 120 -fill red






Is stippling simply not available under [Windows]?  [Bob Techentin] says it's so.
