MadButterfly: include/mb_graph_engine

annotate include/mb_graph_engine_cairo.h @ 465:d8181696b689 Android_Skia

Move functions into graphic engine layers. Cairo and Skia have their own header files and C/C++ files. Some functions are refactoried and move into graphic engine layer to make reset of MadButterfly independently from graphic engines.
