The presentation driver deletes all fonts, patterns, and paths, and resets all attributes to their default values. Note that when resources are not owned by the presentation driver, the driver saves the relevant values so that they are available to reset the device context. A typical example is when the default font is a graphics engine font. In this case, the presentation driver saves the font flags and address passed in the first call to GreDeviceSetAttributes.

The visible region and the DC origin are not affected by this function.
