MadButterfly: include/mb_graph_engine

annotate include/mb_graph_engine_skia.h @ 469:4dc0be6c044a Android_Skia

Add copy and clear graphic engine functions. To replace set/get options, copy and clear is more meanful, functional, and independently. set/get options are too graphic engine dependently.
