* added snap and lock angle to path tool
* fixed breakage of `tab` and `space` functionality
- Previous implementation broke functionality of using Tab to swap the being-dragged handle to its opposing handle, Now fixed.
- Previous implementation broke functionality of using space to drag the manipulator group (anchor + handles) while dragging a handle, Now fixed.
* fixed the angle snapping and locking when used together
Now, if `shift` is used to snap to a 15° increment, then `ctrl` is used to preserve the angle, releasing the `shift` key will still preserve the angle.
* Fix snapping angle logic
* Improve transforms
* added functionality for `alt` key
Now, temporarily converts selected handles to colinear if they are not already colinear.
* Revert "added functionality for `alt` key"
