annotate src/graph_engine_skia.cpp @ 511:caa087976b17 Android_Skia

Fix the issue of segmentation fault when the pattern of a mbe is not setted. For Skia graphic engine, a mbe does not always have a pattern. For example, a color paint does not set a pattern on a mbe for a shape. So, we check if pattern is setted before accessing it.
