Dev:GraphicsServices.framework

GraphicsServices is a CF-like framework that contains a variety of "mid-level" APIs:
 * Capability checking, including
 * Maps restriction.
 * Screen information.
 * Color and font objects management.
 * Event sending.
 * Synchronization with the screen refresh rate.
 * Sampling.

Note that GraphicsServices is one of the more volatile private frameworks. If you need to use this, make sure to check for version compatibility.
