Review the code of MIL-002 against QC-PY-001: 12 of 13 criteria apply and all
pass, criterion 10 is N-A (no Design Class Diagram). Verdict Go, confirmed by
S01. That is the last Go criterion of MIL-002.
Two decisions stay open and do not block the verdict: the tests need a display
for Tk, and a few pale palette colours are faint on the white background.
Closes#13
Task: MIL-002#7
MIL-002 tasks 1 to 6.
- Add create_pen, which hides the turtle, lifts the pen and switches the screen
to 0 to 255 colours.
- Add dot_positions: 100 dot centres in 10 rows of 10, 50 apart, centred on the
origin so the painting fits the default window.
- Add draw_dots, which draws a size-20 dot at every position in a colour chosen
from the palette, and raises ValueError for an empty palette.
- Add main: draw with the palette of the reference image, then wait for a click
with exitonclick. Animation is off while drawing and the screen updates once,
which takes the drawing from 21.1 to 0.35 seconds (SC6 allows 30).
- Add 22 tests: pen setup, positions and spacing, dots on a recording fake pen
and on a real turtle, no trail, and the order of main's steps. All tests share
one hidden Tk window, because starting Tk per test fails now and then on
Windows.
