Bugfix #3494

Browse Source 
An image texture without picture returned a '0', causing the texture code
to generate a bump normal that warped the entire shading around.
In bugreport it was showing terminator issues with ray shadow.

Terminator problems can still occor with more extreme bumpmaps though,
something to look at further.
