src/opts/SkBitmapProcState_opts_arm.cpp:12: #include "SkPreConfig.h"
SkPreConfig is always included by all Sk files (it's included by SkTypes.h) so
it doesn't need to be reincluded here. FWIW, SkPreConfig (along with
SkUserConfig and SkPostConfig) are order dependent, and can't be included
otherwise.
