In `@core/src/input/mouse.rs`:
- Around line 1042-1052: set_controller_visual_mode updates the controller
visual state via controllers_cursors and controller.set_visual_mode_override but
does not trigger a redraw, so the cursor badge can remain stale; after modifying
the controller (inside the if block or immediately after the loop) call the
appropriate redraw trigger on the UI surface (e.g. self.request_redraw() or
self.window.request_redraw()/self.queue_redraw(), depending on the available
API) so the cursor is repainted; reference set_controller_visual_mode,
controllers_cursors, and set_visual_mode_override when locating where to add the
redraw call.
In `@core/src/lib.rs`:
- Around line 1215-1229: The code incorrectly mutates pointer state when
drawing_mode is DrawingMode::Any; change the pointer update logic so
DrawingMode::Any is a no-op: compute visual_mode as currently done
(DrawingMode::Any -> None) but only call
cursor_controller.set_controller_pointer(...) for modes that explicitly set
pointer behavior (e.g., DrawingMode::Draw(_) -> true and
DrawingMode::ClickAnimation -> true, DrawingMode::Disabled -> false), and skip
calling set_controller_pointer for DrawingMode::Any; keep the subsequent call to
cursor_controller.set_controller_visual_mode(sid.as_str(), visual_mode) as-is.

@theodkp thanks for the PR. Generally looks good. One issue is that the pencil has offset from where the draw line ends.
We could either flip the pencil in the svg or maybe when the mode is pencil hardcode an offset in draw in cursor.rs.

I am fine with leaving this as is but I think we can do better. Instead of having two member for tracking the same thing we can just merge the visual mode with mode. This will need more refactoring as we have many functions who assume there are only two cursor modes. If you don't want to give it a go I am fine with leaving a todo comment here and we can improve later.
