L3DT release 1.5 coming very soon

Why another release so soon? SPEED!! Inspiration struck last night and I got the hybrid geometric/fractal overlay height-field generator down to 30 seconds / megapixel (from over 5 minutes). There was no loss of quality. I expect to make release 1.5 available on Monday or Tuesday. The 'tech info' and 'tute' pages will be updated then.
