     23 /*  SkTypes.h, the root of the public header files, does the following trick:
     24 
     25     #include "SkPreConfig.h"
     26     #include "SkUserConfig.h"
     27     #include "SkPostConfig.h"
     28 
     29     SkPreConfig.h runs first, and it is responsible for initializing certain
     30     skia defines.
     31 
     32     SkPostConfig.h runs last, and its job is to just check that the final
     33     defines are consistent (i.e. that we don't have mutually conflicting
     34     defines).
     35 
     36     SkUserConfig.h (this file) runs in the middle. It gets to change or augment
     37     the list of flags initially set in preconfig, and then postconfig checks
     38     that everything still makes sense.
     39 
     40     Below are optional defines that add, subtract, or change default behavior
     41     in Skia. Your port can locally edit this file to enable/disable flags as
     42     you choose, or these can be delared on your command line (i.e. -Dfoo).
     43 
     44     By default, this include file will always default to having all of the flags
     45     commented out, so including it will have no effect.

     53     during development, but will slow things down in a shipping product.
