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!
Correctly tesselate the DistortedBitmap target!
Tesselate DistortedBitmaps better - now all the triangles long edges point at the center of the bitmap, which makes z-distortions look much better!
Minor stuff - make the Bitmaps and the Cubes agree on the size of the grid, mostly.
remove the 'Color' vertex attribute.
Minor: deal with IntelliJ warnings
1. new package 'message'2. Rename the 'Grid' classes to match
