Because of history question black and white colors in bump maps were 
flipped in Blender so white used to mean concavity, black used to mean 
salience. Now it was flipped so white means salience and black means 

We suspended this change for before 2.60 but now it's time for this 
change. I've wrote code which flips normal factor for files created in 
Blender before this change, so this change shouldn't hurt render result.

But some issues are known: if you now open file saved by current trunk 
in, say, Blender 2.59, you'll have wrong render result in 2.59. You can 
do everything needed in 2.59, save file and open it it current trunk and 
render result should be fine again.

Let me know if some special cases are still wrong and it'll be fixed.

Thanks to Morten for patch and Ton for finishing this patch.

With best regards, Sergey I. Sharybin
