A press anywhere on a mask's outline takes hold of it to turn it, and the turn it
asked for was read as an absolute bearing: the direction from the shape's pin to
wherever the finger now happened to be. The outline is a grip a hand lands on
wherever it likes — a ramp's line runs the whole way across the photo — so the
moment a press was set down on it the shape swung round to face that finger. A
press on the edge of a ramp lying across the photo stood it upright on a ten-pixel
move, and a shape already turned snapped to the angle of the press before it had
been dragged at all.
The turn is now what the hand turns: the change in bearing about the pin since the
press, which on the first move is the press itself. A finger that lands on the
outline and stays there leaves the angle exactly as it found it; one that carries
the shape round by a quarter turn turns it by a quarter turn, whatever angle it
was at to begin with. An ellipse adds that turn to the angle it stores, a ramp
spins its two ends about its own middle, and both are measured in the photo's own
pixels so the two bearings are the same kind of thing.
ponytail: The turn is read against the previous pointer position the drag already
keeps, so it costs one subtraction and no state. A pointer that leaves the photo
mid-turn keeps the angle it stood at — the rule the brush already follows — and
the next move on the picture resumes from the last position that was on it.
Verified: tsc clean; mask-probe 52/0 on the dev server and again on 8090 — a press
on a ramp's own edge that travels a hundredth of the photo's width leaves the ramp
at the angle it was taken hold of at (ends 0.500 and 0.500), and on a shape
already turned the same press keeps it upright (0.562,0.260 and 0.558,0.860); a
quarter turn of the hand on the edge turns the ramp a quarter of the way round
(ends 0.200 and 0.800, one pin, no second shape laid); the pin still takes the
shape with the hand to where the hand went (0.560,0.560, no sideways throw); the
rim of an ellipse still turns with the hand on it (1 pin); another chip still
leaves 0 mask columns and the mask chip brings 1 back; DELETE still takes the
chosen shape off the photo with its grade (64 -> 255, then back to 61). Against
the code before this change the same probe fails 9, both angle checks among them —
the ramp lands at 0.850,0.560 and 0.860,0.562, that is, wherever the finger was.
