Retrieves a value that indicates specific capabilities of a transition.
HRESULT value = object.get_Capabilities(long* pVal);
Pointer to a value that indicates the type of image transform.
If the return value has no flags set, the transform type is unknown.
If DXTET_MORPH is set, and if the transform is set up with two inputs, the result at IDXEffect::Progress = 0 is equal to the first input, and the result at IDXEffect::Progress = 1 is equal to the second. This flag is set for all image 1 to image 2 transitions.
If both DXTET_PERIODIC and DXTET_MORPH are specified, and if the transform is set up with only one input, the transform is periodic. If the transform is set up with two inputs, it acts as a morph.
