// First time gfxPrefs::GetSingleton() needs to be called on the main thread,
// before any of the methods accessing the values are used, but after
// the Preferences system has been initialized.
// The static methods to access the preference value are safe to call
// from any thread after that first call.
// To register a preference, you need to add a line in this file using
// the DECL_GFX_PREF macro.
//
// Update argument controls whether we read the preference value and save it
// or connect with a callback. 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). If the value was not set, the default would be false.
//
// In another example, this line in the .h:
// DECL_GFX_PREF(Live,"gl.msaa-level",MSAALevel,uint32_t,2);
// means that every time you call
// uint32_t var = gfxPrefs::MSAALevel();
// from any thread, you will get the most up to date preference value of
// "gl.msaa-level". If the value is not set, the default would be 2.
// Note 1: Changing a preference from Live to Once is now as simple
// as changing the Update argument. If your code worked before, it will
// keep working, and behave as if the user never changes the preference.
// Things are a bit more complicated and perhaps even dangerous when
// going from Once to Live, or indeed setting a preference to be Live
// in the first place, so be careful. 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. For
// example, if the accessor is Foo() then calling SetFoo(...) will update
// the preference and also change the return value of subsequent Foo() calls.
// This is true even for 'Once' prefs which otherwise do not change if the
// pref is updated after initialization. Changing gfxPrefs values in content
// processes will not affect the result in other processes. Changing gfxPrefs
// values in the GPU process is not supported at all.
