1. The algorithm is optimized, and now the modified value will be adjusted according to the overall range of the slider. Obviously this is more reasonable.
2. Added support for Slider of plug-in panel (Slider in all UI in the game is already supported).
Note :
For the Slider of the plug-in panel, because the panel will scroll. So some extra operations are needed: when you need to adjust the Slider, you need to click on the Slider for the first time. After adjusting the Slider, when you need to scroll the plug-in panel, you need to click once in the blank space of the plug-in panel (or in the non-UI area of the game).
