Distorted Android

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!

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.

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

Convert Wind app to the stretch-less API.

A lot of changes.

1) main vertex shader: remove support for degree_object. This functionality will hopefully come back when we introduce other than circular regions.
2) MeshBase: remove the need to set a Bounding box (this is the point of the whole thing - we wanted to get rid of this so that the advances in MeshJoined will be easier)...

All apps converted to the new V&F center schema!

Fixes for the merge.

Merge branch 'empty-matrix-effects-in-the-center' into modern-empty-matrix-effects-in-the-center

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)
