A composition that performs a transition between two images, using a parametric time value to drives the transition from start (at time 0) to end (at time 1). A conforming composition must use the input keys QCCompositionInputImageKey for the starting image and QCCompositionInputDestinationImageKey for the ending image. The composition can optionally use QCCompositionInputPreviewModeKey to indicate if the animation should run in lower-quality for preview purposes.
