Distorted Android

Improve the Blur App to catch the bug where a small part of the Blur (and Glow) halo gets displayed on the other edge of the surface.

We need to pause an Activity in the following way:

1) Activity.onPause()
2) View.onPause()
3) Library.onPause()

otherwise sometimes there are artifacts when pausing!

Make the MeshFile app survive a period of being paused.

1) rename DistortedTexture's setColor to setColorARGB
2) fix the Wiind app to take into account paused time
3) fix the Dynamic so that if a single Dynamic is used more than once (in more than one effect) than it doesn't get adjusted for paused time multiple times.

Before somehow the Dynamics sometimes tolerated not being reset to beginning before next use. New version doesn't - correct that in two apps.

Fixes for pausing and restarting.

Only compile the Full, Normal & OIT programs when they are actually needed.

Example meshes for the MeshFile app.

Library: introduce a new form of the MeshRectangular grid, where the individual rows and columns can be each of different width. This help reduce the number of vertices in objects as typically we are only interested at distorting a certain subregion.

Modify the Bean app to take advantage of this.
