For devices that support fixed frame sizes. Defined sizes match typical page sizes. This specifies the size(s) the Source can/should use to acquire image data. Note: TWSS_B has been removed from the specification.
The frame size selected by using this capability should be reflected in the TW_IMAGELAYOUT structure information.
If the Source cannot acquire the exact frame size specified by the application, it should provide the closest possible size (preferably acquiring an image that is larger than the requested frame in both axes).
For devices that support physical dimensions TWSS_NONE indicates that the maximum image size supported by the device is to be used. Devices that do not support physical dimensions should not support this capability. Note: TWSS_MAXSIZE has been added to simplify negotiating for the entire acquisition area of a device, since TWSS_NONE was overloaded to mean both “a custom frame” and “the maximum image size.”

For instance, use TWSS_A instead of TWSS_A LETTER (note that the values are the same, the reason for the new constants is to improve naming clarification and consistency). Additions
