Major change in API: separate the GRID from DistortedObject; completely remove classes derived from DistortedObject.
DistortedFramebuffer should we working now, including deletions.
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
