Speedup for preapply

1 more fix for MeshBase.apply(VertexEffect). This still does not (fully) work though.

3 fixes for MeshBase.apply(VertexEffect).
This still does not work though.

Progress with the Predeform app; deepCopy for the Meshes; various fixes.

Progress (?) with Predeform: give up trying to render the Mesh in Activity1.

First attempt at the MeshBase.apply(VertexEffect) API.

Remove the MeshBase.{set/get}Stretch API altogether.

Fix for a crash when exiting an app:

Activity.onPause() -> MessageSender.stopSending sets mThis to null, then a last message gets sent and a crash in newMessage().

Fix this by

1) making the Message inner class static (so that we can create a new one without a reference to mThis)...

Change the Postprocessing effects: separate the radius and the halo.
Reason: we needed a way to specify the size of the halo around a postprocessed object; before it was automatically (and not very correctly) computed from the radius - before we knew the size of the object's bounding box, so this automatic computation was possible. Now we're removing the MashBase.getBounding(0 API, so the size of the halo has to be explicitly given by the user. This way is more correct anyway and gives the user more control (as the Multiblur app proves!)...

Simplify a bit the place where we got a crash once.
