2.4x) from within Freestyle. Now Freestyle configuration parameters are edited without relying on the notion of the current scene. This resolved a few related issues as described below: - A bug in Freestyle configuration management with respect to multiple scenes was fixed. Now Freestyle configuration parameters (e.g., style modules, ridges/valleys, suggestive contours) can be specified for each render layer of each scene. Composition of multiple render layers from different scenes should work as expected. - A crash after undoing was fixed as well. * Removed unused external Freestyle functions and global variables from FRS_freestyle.h and FRS_freestyle.cpp.
