[Bf-committers] Bump mapping computation issue

[Ton Roosendaal]

Hi,

Here's some results;

http://download.blender.org/demo/test/camrot_real.avi

The plane rotates, and camera is child of plane (so effectively the  
lamp rotates).
The last one is a nurbs surface to verify it. It's very hard in this  
situation to see the actual improvement, but watching the outer rings  
you can see it.

The error in the old code is much more evident in this case;

This brought buddy Chris Burt on irc to point me to this;

Here's the bump only;
