way to evenly space a selection of keyframes.
In order to select multiple keyframes, you can either click on them with the Shift key held
down or simply click with your mouse on an empty area on the Timeline (where the key-
frames are) and start dragging. This will draw a selection rectangle that will select all key-
frames inside the rectangle when you let go of the mouse button.

With the three sprite frame animation keyframes selected, select the Animation Stretch
