The opening paragraph of the class docs in each of the following classes has a grammatical error:

FadeTransition
PathTransition
RotateTransition
ScaleTransition
TranslateTransition

Taking the latter as an example, the first two sentences read:

"This Transition creates a move/translate animation that spans its duration. This is done by updating the translateX, translateY and translateZ variables of the node at regular interval."

The last word should be "intervals" (plurals).
