Worked on the libsdl-org/SDL repository to standardize pinch gesture end events across mobile platforms, focusing on reducing JNI interface complexity and improving event consistency. Addressed a bug by removing unnecessary coordinate data from end events and emitting dummy values, which streamlined the integration process for mobile builds. Updated documentation and internal event handling logic to clarify that only begin and update events require coordinate data, making the codebase more maintainable and onboarding easier for developers. Utilized C, Java, and JNI to implement these changes, ensuring a more predictable mobile user experience and providing clear traceability for future audits and maintenance.
