Previously mesh vertices imported from vlak nodes were transformed
from the camera coordinate system to the object local coordinate
system. This causes a difficulty in recovering object local vertices
when mesh deforming modifiers (e.g., curve, cloth, and soft body) have
been applied. Now the view map creation is done based on mesh
vertices in the camera coordinate system. Advantages of this approach
includes: 1) faster mesh importing because of less matrix-based
transformations; and 2) proper handling of meshes with deforming
modifiers.
instability issues regarding the view map creation. A new iterative
solver of the 2D-to-3D inverse projection transformation problem was
implemented. Instead of directly solving the problem in the direction
from the 2D to 3D space, the new solver starts with an initial guess of
an approximated solution and asymptotically approaches to the true
solution by iteratively performing the forward 3D-to-2D projection
transformation and improving the approximation. Preliminary tests with
one simple and another complex scenes showed that the solver converges
quickly (more and less 20 iterations in many cases, with a stopping
criterion of a residual distance between the true and approximated
solutions less than 1e-6 Blender Unit).
from within style modules. Calling this function is only valid within
style modules. Calling it from the Python Interactive Console results
in an error as follows:

>>> Freestyle.getCurrentScene()
Traceback (most recent call last):

initializing Freestyle and specifying contexts, making the API a bit messy.
Now FRS_initialize() is only for initialization, and contexts are specified
by new FRS_set_context() function just before starting rendering.
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.
