Move the Effects.setStretch to Meshbase.setStretch
Move the 'pre-multiply mesh before applying any effects' thing from [(Xsize of texture, Ysize of texture) x Mesh's zFactor] to Effects.setStretch(sx,sy,sz)
remove an unused, redundant API.
Simplify the way applications can get notifications when an effect finishes.
Now, instead of the 'DistortedEffects.(de)registerForNotifications()' 2 APIs, we call a single 'Effect.notifyWhenFinished()'.
Correct the Legal notice.
Rename all the classes that are not exported to application to 'Internal'
Finally move the EffectQueues to their own package.
