POV-Ray

This is the first in the POVWIN beta series to have a full installer (provided as a Microsoft Installer .MSI file). While not a final version of the installer (currently it only installs for one user), it`s a step in the right direction. The beta should be much more Vista-friendly as a result of this and some internal changes to the location files are stored.Changes:Added ARRAYS_WriteDF3 macro to arrays.inc for writing an array to a df3 file. Fixed bug creating Artifacts in output file when mosaic preview is used with +EP2 and -A. Several Unix build fixes. Added Radiosity octree performance stats and fixed stats for max trace level & parse time. Made some improvements to performance in crackle Cache, and optimised the management of thecrackle cache size by setting limits in megabytes (currently per-thread and not user- settable: this will change).
