[Nathan Letwory]

Hi,

I got uneasy with the almost visibly unnoticable changes in depth in
output, that I wrote a small patch (attached to mail.)

The patch searches first for second highest float (= geom pixel farthest
away). Then uses that to convert other float values of zbuf to nice 0-255
range. Changes only writeimage.c

Kent, perhaps you want to check it? Or anyone for that matter :)

ps. apply in source/blender/src
