The RestoreDC function restores a device context (DC) to the specified
state. The DC is restored by popping state information off a stack
created by earlier calls to the SaveDC function.
BOOL RestoreDC(
HDC hdc, // handle to DC
int nSavedDC // restore state
);
Parameters
nSavedDC [in] Specifies the saved state to be restored. If this parameter
is positive, nSavedDC represents a specific instance of the state to be
restored. If this parameter is negative, nSavedDC represents an instance
relative to the current state. For example, �1 restores the most recently
saved state.
