Keyframe icons

The appearance of a keyframe icon depends on where it is on the track. The default (first and last) keyframes are white rectangles ()that rest at the edges of the clip. Once you add additional keyframes (), the initial keyframes become white half-diamonds. Once you move the keyframes from the edges, they become full diamonds. The first keyframe is gray on the left half (), and the last keyframe is gray on the right half ().
