/*  SkTypes.h, the root of the public header files, includes this file
    SkUserConfig.h after first initializing certain Skia defines, letting
    this file change or augment those flags.

    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 declared on your command line (i.e. -Dfoo).

    By default, this #include file will always default to having all the flags
    commented out, so including it will have no effect.

/*  Skia has lots of debug-only code. Often this is just null checks or other
    parameter checking, but sometimes it can be quite intrusive (e.g. check that
    each 32bit pixel is in premultiplied form). This code can be very useful
    during development, but will slow things down in a shipping product.

    By default, these mutually exclusive flags are defined in SkTypes.h,
    based on the presence or absence of NDEBUG, but that decision can be changed
    here.
