* Delegate implementing the native methods of android.graphics.ComposeShader
*
* Through the layoutlib_create tool, the original native methods of ComposeShader 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 ComposeShader 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
