== Action Editor - Long Keyframes ==

Now Long-Keyframes in the Action Editor (yellow/pink strips between keyframes) take into account whether the keyframe handles which help control the interpolation between the two keyframes stay at the same value as the keyframes do. 
This way, long keyframes are not drawn when the keys have the same value, but there's still movement between them.
