Zoomlt：hope add Graphics tablet support

### Description of the new feature / enhancement

I often use a graphics tablet to write on ZoomIt, but there is no cursor positioning point. I hope support for graphics tablet functions can be added.

### Scenario when this would be used?

Teaching Scenarios and Learning Scenarios

### Supporting information

_No response_

No files, tests, or entry points are named. Start by locating ZoomIt's input-handling and cursor-positioning code, then determine the graphics tablet behavior required for teaching and learning scenarios. Done would mean supported tablet input provides a usable cursor positioning point in ZoomIt.
