Fix middle-drag smoothness and add compatibility for some apps (#104)

* Refactor mouse event handling to use current position instead of target position; optimize touch data copying in MultitouchManager to reduce GC pressure.

* Add accumulated drag position and cursor reassociation in MouseEventGenerator

- Introduced `lastDragPosition` to track the accumulated drag position for improved cursor handling in applications requiring absolute positioning.
- Added `reassociateCursor` method to restore normal cursor behavior after drag operations.
- Updated drag handling to use accumulated position for mouse events, enhancing compatibility with various applications.
- Ensured cursor is properly reassociated after drag ends or is canceled to prevent freezing issues.

* Enhance cursor re-association error handling in MouseEventGenerator; optimize touch data copying in MultitouchManager to reduce GC pressure

* Refactor MouseEventGenerator to improve drag position handling and add clamping to display bounds; enhance test coverage for drag position accumulation and clamping behavior

* Enhance display bounds caching and reconfiguration handling in MouseEventGenerator; ensure atomic cursor reassociation during drag release to prevent race conditions

* Refactor delta field setting in MouseEventGenerator to ensure proper order of double and integer values for improved compatibility with various applications

* Refactor MouseEventGenerator to ensure atomic cursor reassociation and state updates during drag cancellation, preventing race conditions and improving drag state management.

* Refactor MouseEventGenerator to ensure atomic cursor reassociation and drag state updates during normal drag termination, preventing race conditions and enhancing overall drag state management.

* Refactor MouseEventGenerator to enhance drag state management by ensuring atomic cancellation of existing drags, preventing race conditions during new drag initiation.
