 TODO
 
+* transitions are immutable, too; *transition*.merge
+* *transition*.each ↦ *transition*.on
+* *transition*.each is now the same as *selection*.each
+* new d3.active for chaining transitions / modifying in-progress transitions
+* new *selection*.transition(*transition*); searches ancestors
+* new d3.interrupt
+* change *transition*.transition semantics in regards to *transition*.delay
+* strict state machine to enforce when transitions can be modified; more robust
+* enforces *t* = 1 on end
+* functions passed to transition methods take the same standard arguments as selections
+* optimize transitions to re-use tweens and interpolators to improve performance!
+* *transition*.attrTween gets standard arguments (not current attribute value)
+* *transition*.styleTween gets standard arguments (not current style value)
+* call *transition*.{tween,attrTween,styleTween} in getter mode
+* uses optimized interpolator rather than d3.interpolate
+* fix *transition*.remove if multiple transition names are in use
+* new *transition*.selection
