While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

These qualifiers were leftovers of the stand alone Freestyle program and not used
(set to an empty string) in Blender for years.

A crash in the Freestyle renderer was reported by Ton on IRC with a stack trace
below. Note that #2 is in Freestyle, whereas #1 is in the compositor. The problem
was observed in a debug build on OS X 10.7 (gcc 4.2, openmp disabled, no llvm).

Apparently a name conflict between the two Blender modules is taking place.
The present commit hence intends to address it by putting all the Freestyle C++
classes in the namespace 'Freestyle'. This revision will also prevent potential
name conflicts with other Blender modules in the future.
Special thanks to Lukas Toenne for the help with C++ namespace.

this can be added back on case-by-case basis, but better not assume ownership of another projects work by default.
|

|

Now the code style is acceptable for the merge now, according to Bastien.
Thanks again Bastien for having this done! :)

Reported by Bastien Montagne, thanks!

The instability considered here is due to a persistent failure of the
getFEdge() method in the Interface0D class and its subclasses in the
presence of smooth FEdges. When the Face Smoothness option is
enabled, the view map is populated with not only sharp FEdges (i.e.,
edges in the original meshes) but also smooth FEdges (i.e., newly
built edges lying on triangular surfaces). The failure of getFEdge()
caused many related issues because the method is widely used in other
predicates and functions that rely on it. The most prominent example
of related user-visible problems is a constant failure of the built-in
MaterialF0D.
The main issue and related problems were addressed as follows:
* A bug in the construction of smooth FEdges was fixed. Individual
smooth FEdges, even when they were detected as a series of smooth
FEdges that constitute one smooth ViewEdge, may have some irregular
geometry in the form of non-uniform OWXFaceLayer::order values. The
OWXFaceLayer::order values were used in an inappropriate way, so that
resulting smooth ViewEdges may have an FEdge between two subsequent
SVertices that were indeed the same SVertex object. This was an
unexpected situation that getFEdge() could not handle.
* Another issue in the construction of smooth FEdges was resolved.
When sharp FEdges are constructed, two SVertices at both ends of an
FEdge are generated only when no SVertex exists in a given 3D position
(this way, the original mesh topology is reconstructed from a bunch of
independent triangles that the BlenderFileLoader class passes to the
view map creation process). This sharing of SVertices was used also
for the generation of SVertices at the two ends of each smooth FEdge,
causing the getFEdge() failure in the presence of smooth FEdges. The
workaround implemented here is to simply suppress the sharing of
generated SVertices when smooth FEdges are created.
* In the Parameter Editor mode, the built-in MaterialF0D was replaced
with a better implementation that works well with Curves and Strokes.
MaterialF0D does not work with these 1D data types.

IMPORTANT: The setters functions' names were normalized due to constant confusion regarding capitalization. All the function names start with set... instead of Set.... This convention was changed all throughout Freestyle. To use Freestyle as an external renderer, the SWIG library MUST be regenerated.
