... does not restore the measure points
Halt the measure tool after straightening, thus removing the
expectation that undoing the operation should restore the original
points.
Halting the tool, rather than making undo work "as expected",
sidesteps several issues:
- Implementing undo correctly is tricky, since image-undo and
tool-undo are handled separately.
- In fact, the measure tool doesn't provide tool-undo, so that
image edits can be undone while the tool is active without
affecting the tool, and it's not clear that we want to change
this behavior. However, this makes undoing a straighten
operation a special case, and it's not entirely clear what the
behavior should be when undoing other kinds of transformations,
or when the measure points had changed since the straighten
operation.
- Perhaps most importantly, measure tool points are restricted to
the pixel grid, which means that when measuring an angle
against an orientation that's not fully horizontal or vertical
in image space (either using a 3-point angle, or when the
canvas is rotated), the resulting transformed point after
straightening doesn't generally land on the pixel grid, causing
it to be rounded, which can result in a non-zero angle after
the rotation. This is especially ugly, since clicking
"straighten" again at this point would cause another non-
trivial rotation.
