Release notes for 583

The Mac Client now supports input from all input method editors.

Enables Lua-based Character State Machine.

Adds GetMoveVelocity method in Humanoid to retrieve humanoid movement velocity based on the player input.

Controllers now have a property called Active that indicates whether they are currently active.

Removes AirController.LinearImpulse in favor of calling BasePart:ApplyImpulse.

Improves the performance of code under the workspace which is bottlenecked on property sets by ~3%. This includes things like scaling, moving, and changing the transparency of models.

Changes DragDetector.AddConstraintFunction API to return ScriptConnection, removes name argument, and removes DragDetector.RemoveConstraintFunction API.

Settings dialog no longer prompts you to restart Studio when closed unless you changed one of the few settings which actually requires a Studio restart to take effect.

Within the Tag Editor in Studio, the option to visualize a tag with its name in the viewport is now a separate checkbox, allowing the tag name visualization to be combined with the other visualization types.

ClickDetectors now correctly check distance to characters without a Humanoid in them.

Fixes a bug where Vehicles that used OneAttachmentMode constraints would have issues properly assigning physics ownership to players sitting in them.

Fixes an issue where newly added descendants of PlayerGui are not always copied when atomic characters are used.

Fixes missing Lock tool icon.

When dragging a part using DragDetectors, if the drag is interrupted, the drag will be properly canceled and cleaned up. The interruptions handled are deletion of the DragDetector, setting the DragDetector to enabled = false, player respawning, player leaving game, and launching of player menu.

Fixes toolbox asset preview voting buttons being incorrectly highlighted.
