描述

Hi,

First of all, great project! Do you plan to implement Pan and Zoom at the same time with touch events? It seems like you can only zoom or pan and not both.

Maybe I can help to contribute if the library is not restricted in anyway.

研究方向
Review the current touch event handling code in the library (likely in the main JavaScript file). Identify how single touch pan and pinch to zoom are currently implemented separately. Investigate if there is existing support for multi touch gestures that could be combined. Check for any related issues or PRs that discuss simultaneous pan and zoom.
