23/**
24 * Delegate implementing the native methods of android.graphics.CornerPathEffect
25 *
26 * Through the layoutlib_create tool, the original native methods of CornerPathEffect have been
27 * replaced by calls to methods of the same name in this delegate class.
28 *
29 * This class behaves like the original native implementation, but in Java, keeping previously
30 * native data into its own objects and mapping them to int that are sent back and forth between
31 * it and the original CornerPathEffect class.
32 *
33 * Because this extends {@link Shader_Delegate}, there's no need to use a {@link DelegateManager},
34 * as all the Shader classes will be added to the manager owned by {@link Shader_Delegate}.
35 *
