There was a subtle bug in computation of derivatives in some extreme cases when ray-tracing in mantra. This intermittent bug might have caused NAN's or even possibly crashes in ray-traced images (including global illumination). Most notably, there was a specific bad case when ray-tracing against open polygons.

Added a display preference, "Fast Pixel Aspect Ratio Display", which is on by default. When on, a simple horizontal pixel scale is applied in hardware to any image with pixel aspect ratio that isn't 1. When off, a slower software box filter scale is used, which eliminates the artifacts that are present in the hardware scale.

This is only noticable for fractional aspect ratios - integer aspects such as 2 (or 1/2, 1/3) work just as well in Fast mode.

This also applies to the Halo viewer.

-w <width> and -h <height> now work for loading files. Previously they only work for specifying the size of files read in by stdin. All files loaded on the command line will by loaded at width x height, regardless of their natural size.

Fixed a problem with loading images from the file browser in mplay. They would load up as black frames.

Added "Set Current Values to Defaults" menu entry to Presets menu. It behaves as the corresponding entry in the parm menu, but does so for the entire set of parameters.
