  - Enable use of other meshes for shadow mesh generation, can be used to speed up shadow generation and rendering for complex meshes. Patch based on a version by tonic.
 
- - Fixed Software renderer color flicker, was a signed shift bug I believe.
-
  - Fixed usage of SIrrCreationParameters struct, which dind't have copy constructor and assignment operator anymore, since the Irrlicht version string was made const.
 
  - New glext.h (version 40)
