I guess I've posted an image showcasing this patch before, but now that 
I'm actually preparing it for a release (not into POV-Ray proper, but an 
unofficial branch I'm currently compiling from various fancy patches 
that have accumulated in my drawer) and have finally tracked down a 
serious performance issue, i thought I might post another set of 
demonstration renders.

The first image was rendered with the standard anti-aliasing mode 2, 
taking 6 seconds to compute. Note the moiree effects near the horizon, 
which are resistent to any increase in anti-aliasing quality settings.

The second image was rendered with the new anti-aliasing mode, taking 
only 5 seconds to compute. Note how the distant moiree is replaced by 
random noise.

The third image demonstrates the increase in render quality that can be 
achieved by cranking up the anti-aliasing quality settings. Moiree 
patterns begin to show again, but they are less pronounced than with 
anti-aliasing mode 2 (which, as I love to re-iterate, will not get any 
better whatever you do). Render time was 84 seconds.


(Render times are comparatively long for such a simple scene because I 
was using a debug version of the binary, with plenty of compiler 
optimizations turned off.)
