Description

Normalize absolute mouse motion on macOS to the event-provided coordinate space instead of using display scaling assumptions, with clamping to valid source bounds before mapping to display coordinates. This also clarifies public API docs for absolute and fractional coordinates, adds test hooks and unit coverage for coordinate conversion behavior, and expands runtime mouse tests to assert absolute event fields for both integer and fractional submissions.
