LayoutLib: support for Path and BitmapShader using delegates.
Also created delegates for all missing shader, xfermode
and patheffect classes. Moved the logic of the xfermode,
and patheffects that was in Canvas_Delegate into the
xfermode/patheffect classes, and added support (in all
3 clases) for knowing if the shader/xfermode/patheffect
is actually supported or not. Make use of fidelityWarning
in LayoutLog if they are not.

+ * 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}.
