Merge changes from topic "HWUI_JNI"
* changes: Export symbols for the newly exposed APEX/internal headers Remove dependence on libandroid_runtime from Bitmap.cpp Update Region.cpp to use AParcel NDK APIs Cleanup header and build targets for libhwui clients. Remove dependencies on headers outside UI module Cleanup LOG_TAG when bundled in HWUI Move android.graphics JNI & APEX files into HWUI
