Remarks
The attribute value is an MFVideoArea structure.
This attribute is used to crop widescreen video to a 4:3 aspect ratio. The pan/scan aperture is used only in pan/scan mode, which is enabled by setting the MF_MT_PAN_SCAN_ENABLED attribute to TRUE.
If pan/scan mode is not enabled, use the display aperture, specified by the MF_MT_MINIMUM_DISPLAY_APERTURE attribute.
If this attribute is not set, the pan/scan aperture is assumed to be the entire video frame.
The GUID constant for this attribute is exported from mfuuid.lib.
