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