/* SkTypes.h, the root of the public header files, does the following trick:
#include "SkPreConfig.h"
#include "SkUserConfig.h"
#include "SkPostConfig.h"
SkPreConfig.h runs first, and it is responsible for initializing certain
skia defines.
SkPostConfig.h runs last, and its job is to just check that the final
defines are consistent (i.e. that we don't have mutually conflicting
defines).
SkUserConfig.h (this file) runs in the middle. It gets to change or augment
the list of flags initially set in preconfig, and then postconfig checks
that everything still makes sense.
Below are optional defines that add, subtract, or change default behavior
in Skia. Your port can locally edit this file to enable/disable flags as
you choose, or these can be delared on your command line (i.e. -Dfoo).
By default, this include file will always default to having all of the flags
commented out, so including it will have no effect.
