Undo splitting of buffers in three. Makes buffer access much faster

Not kidding here. For the default parameters this increased the maximum pixel brightness in the image by a factor of 2.25.
This has the drawback that the maximum possible image size got reduced, but hey, there's a command line switch to ignore all size limits ;-)
