-/**
- * 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
