/* 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.
