See UpdatePolicy enum below. +// Pref is the string with the preference name. +// Name argument is the name of the static function to create. +// Type is the type of the preference - bool, int32_t, uint32_t. +// Default is the default value for the preference. +// +// For example this line in the .h: +// DECL_GFX_PREF(Once,"layers.dump",LayersDump,bool,false); +// means that you can call +// bool var = gfxPrefs::LayersDump(); +// from any thread, but that you will only get the preference value of +// "layers.dump" as it was set at the start of the session (subject to +// note 2 below).

You need to be ready for the +// values changing mid execution, and if you're using those preferences +// in any setup and initialization, you may need to do extra work. + +// Note 2: Prefs can be set by using the corresponding Set method.
