ncicandClaude Opus 5.5 21a9e854e1 Tools: only the freehand tools get every move of a frame (#4227 review)
Every pointer move of a frame went to whatever tool was active, so with
a fast mouse (or a pen) a tool whose drag preview is costly (the
Selection tool moving a large selection, Free Distort, the Width tool)
redid it for each, up to 64 times a frame.

Tool::wants_samples (default false) says a tool builds a stroke from
the drag's samples: the Pencil, Paintbrush, Blob Brush, Eraser, Knife,
Smooth and Path Eraser answer true (the Paintbrush through its wrapper),
the Join tool doesn't. The canvas still reads the frame's moves every
frame, so the macOS feed's pressures stay paired, but replays them only
to such a tool; every other tool gets one drag a frame at the latest
position. A frame whose moves end where the last frame's did still
reaches the tool.

Tests: only_the_freehand_tools_get_every_move_of_a_frame (Pencil,
Paintbrush and Blob Brush get the 19 moves before the last, Selection,
Direct Selection and Width none),
a_mouse_stroke_keeps_a_frame_that_ends_where_it_started,
the_freehand_tools_want_every_sample, and
a_mouse_stroke_keeps_every_move_of_a_frame now checks every position in
order, not only the count.
