Images rendered with 3.7beta12 seem noticeably brighter than the same
image rendered with 3.6 (even when no assumed_gamma of any kind is used
in the scene). Seems to be some gamma issue still.
For example, try textures/patterns/fractals1.pov for a remarkable
difference.
For some reason advanced/bwstripe.pov renders very differently in
3.7beta12 than in 3.6.

this is due to the way we handle color ranges and AA in particular. bwstripe
uses a 'trick' to get the striping (very high brightness values), and that
trick was dependent on the way POV handled these (particularly at what point
the pixels were truncated to 1.0).

I actually got this morning the wild idea that perhaps, just perhaps,
the effect seen with bwstripe.pov is the result of some experimental
antialiasing algorithm which handles the problems in the pov3.6 antialiasing.
However, when I made a simple test with an overbright object, the edge
was still pixelated. So I suppose I was wrong. :(
