Distorted Android

Fix the 'PlainMonaLisa' to be able to run in the Emulator as well (before ELG Context creation would fail)

Preparation to make the WAVE effect fully 3D

Beginnings of the WAVE effect.

Correct an important bug in the vertex shader.

b = 1/a if a!=0, 1 otherwise was incorrectly computed as b = 1.0 / (a+1.0-sign(a)). This, when 0<a<2^-24, suffers from 'round-off error': then a+1.0 = 1.0 (sic!) thus b = 1/0 !.

Correct way: b = 1.0 / ( a - (sign(a)-1.0) )

Fixes for fragment effects in Effects3D.

Slight improvement for Effects3D

Combine Fragment3D and Vertex3D apps into one.

Remove the MACROBLOCK Effect altogether.

Fix the 'Fragment3D' app

Fix the 'FBO' app

Fix the 'Effects2D' app

Fix the 'Different Effects' app

Fix the 'Moving Effects' app

Fix the 'Macroblock' app.

Finally fix the 'when rendering though an FBO, the other side of triangles is visible'

Fix the 1x1 case! Before it used to be impossible to create a DistortedBitmap just with 2 triangles!

Minor stuff - make the Bitmaps and the Cubes agree on the size of the grid, mostly.

Vertex3D: make the Activity independent of Effects

Vertex3D: app finished!

Vertex3D: fix region size.

Vertex3D: Add the new 'Grid' bitmap option!

Vertex3D: Correct setting regions (correction!)

Vertex3D: Correct setting regions.

Add the missing 'Region' resource.

beginnings of support for drawing the Region in Vertex3D app.
