Hit testing: Determining whether a specified coordinate (point) or geometry is contained within the bounds of a visual.
命中测试：确定指定的坐标(点)或几何图形是否包含在可视对象的边界内。
Provides services and properties that are common to all visual objects, including hit-testing, coordinate transformation, and bounding-box calculations.
提供所有可视对象通用的服务和属性，其中包括命中测试、坐标转换和边界框计算。
