1.17 +
1.18 + #include "SkPreConfig.h"
1.19 + #include "SkUserConfig.h"
1.20 + #include "SkPostConfig.h"
1.21 +
1.22 + SkPreConfig.h runs first, and it is responsible for initializing certain
1.23 + skia defines.
1.24 +
1.25 + SkPostConfig.h runs last, and its job is to just check that the final
1.26 + defines are consistent (i.e. that we don't have mutually conflicting
1.27 + defines).
1.28 +
1.29 + SkUserConfig.h (this file) runs in the middle. It gets to change or augment
1.30 + the list of flags initially set in preconfig, and then postconfig checks
1.31 + that everything still makes sense.
1.32 +
1.33 + Below are optional defines that add, subtract, or change default behavior
1.34 + in Skia. Your port can locally edit this file to enable/disable flags as
1.35 + you choose, or these can be delared on your command line (i.e. -Dfoo).
1.36 +
1.37 + By default, this include file will always default to having all of the flags
1.38 + commented out, so including it will have no effect.
