22/**
23 * Delegate implementing the native methods of android.graphics.LayerRasterizer
24 *
25 * Through the layoutlib_create tool, the original native methods of LayerRasterizer have
26 * been replaced by calls to methods of the same name in this delegate class.
27 *
28 * This class behaves like the original native implementation, but in Java, keeping previously
29 * native data into its own objects and mapping them to int that are sent back and forth between
30 * it and the original LayerRasterizer class.
31 *
32 * Because this extends {@link Rasterizer_Delegate}, there's no need to use a
33 * {@link DelegateManager}, as all the Shader classes will be added to the manager
34 * owned by {@link Rasterizer_Delegate}.
