This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

The problem addressed here is that there was no mean to check if an iterator
points the last of the elements being iterated over. Such checking is necessary
to reliably dereference the iterator (i.e., calling the operator*() method of the
underlying C++ iterator object).
Now Interface0DIterator and StrokeVertexIterator have an .at_last property
to check if an iterator points the last element. Using this new API feature,
the present commit partly reverts the previous commit rBeb8964fb7f19 to
better address T41464.

directions at TVertices.
A description of the problem is found in https://developer.blender.org/T36425#19 .
The cause of the issue was identified as roudning errors in Operators::createStroke() due
to insufficient numerical precision. Precision promotion from float to double was done in
the return values of getPoint3D/2D methods in Interface0D and its subclasses in C++
(data members stored in the 0D classes have already been in double precision).

(See commit e1771e72fbbf828dbf5bed871b814288389f3611 for more detail of
the problem).
Made changes to intern/view_map/Interface0D.h and intern/python/Director.h to
avoid #include <Python.h> and keep non-Python header files independent of it.

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.

* Added to python/BPy_Convert.{cpp,h} 4 utility converters below for
better introspection-based automatic type conversion.
PyObject * Any_BPy_Interface0D_from_Interface0D( Interface0D& if0D );
PyObject * Any_BPy_Interface1D_from_Interface1D( Interface1D& if1D );
PyObject * Any_BPy_FEdge_from_FEdge( FEdge& fe );
PyObject * Any_BPy_ViewVertex_from_ViewVertex( ViewVertex& vv );
There are 4 corresponding converters without the "Any_" prefix. All
calls of them in the code base were replaced with these new converters
so that the introspection-based automatic conversion would take place
universally.
* python/BPy_Convert.{cpp,h}: Those C++ to Python converters having
had a "_ptr" suffix were renamed to a name without the suffix, and
their arguments were changed so as to take a reference (e.g.,
ViewVertex&) instead of a pointer (e.g., ViewVertex *). The changed
converters and their new function prototypes are listed below. These
converters now return a Python wrapper object that retains the passed
reference, instead of retaining a newly created C++ object by the
converters.
// Interface0D converters
PyObject * BPy_Interface0D_from_Interface0D( Interface0D& if0D );
PyObject * BPy_CurvePoint_from_CurvePoint( CurvePoint& cp );
PyObject * BPy_StrokeVertex_from_StrokeVertex( StrokeVertex& sv );
PyObject * BPy_SVertex_from_SVertex( SVertex& sv );
PyObject * BPy_ViewVertex_from_ViewVertex( ViewVertex& vv );
PyObject * BPy_TVertex_from_TVertex( TVertex& tv );
PyObject * BPy_NonTVertex_from_NonTVertex( NonTVertex& ntv );
// Interface1D converters
PyObject * BPy_Interface1D_from_Interface1D( Interface1D& if1D );
PyObject * BPy_Chain_from_Chain( Chain& c );
PyObject * BPy_FEdge_from_FEdge( FEdge& fe );
PyObject * BPy_FEdgeSharp_from_FEdgeSharp( FEdgeSharp& fes );
PyObject * BPy_FEdgeSmooth_from_FEdgeSmooth( FEdgeSmooth& fes );
PyObject * BPy_Stroke_from_Stroke( Stroke& s );
PyObject * BPy_ViewEdge_from_ViewEdge( ViewEdge& ve );
PyObject * BPy_directedViewEdge_from_directedViewEdge( ViewVertex::directedViewEdge& dve );
// some other converters
PyObject * BPy_ViewShape_from_ViewShape( ViewShape& vs );
PyObject * BPy_SShape_from_SShape( SShape& ss );
PyObject * BPy_FrsMaterial_from_FrsMaterial( FrsMaterial& m );
PyObject * BPy_StrokeAttribute_from_StrokeAttribute( StrokeAttribute& sa );
* Added a "borrowed" flag to the definitions of Python types being
used to wrap C++ components of Freestyle's internal data structures.
The flag indicates whether or not a Python wrapper object has a
reference to a C++ object that comprises the internal data structures.
The deallocation routines of the Python types check this flag and
release a wrapped C++ object only when it is not part of the internal
data structures. The following files were modified:
python/BPy_FrsMaterial.{cpp,h}
python/BPy_Interface0D.{cpp,h}
python/BPy_Interface1D.{cpp,h}
python/BPy_SShape.{cpp,h}
python/BPy_StrokeAttribute.{cpp,h}
python/BPy_ViewShape.{cpp,h}
python/Interface0D/BPy_CurvePoint.cpp
python/Interface0D/BPy_SVertex.cpp
python/Interface0D/BPy_ViewVertex.cpp
python/Interface0D/CurvePoint/BPy_StrokeVertex.cpp
python/Interface0D/ViewVertex/BPy_NonTVertex.cpp
python/Interface0D/ViewVertex/BPy_TVertex.cpp
python/Interface1D/BPy_FEdge.cpp
python/Interface1D/BPy_FrsCurve.cpp
python/Interface1D/BPy_Stroke.cpp
python/Interface1D/BPy_ViewEdge.cpp
python/Interface1D/Curve/BPy_Chain.cpp
python/Interface1D/FEdge/BPy_FEdgeSharp.cpp
python/Interface1D/FEdge/BPy_FEdgeSmooth.cpp
* view_map/Interface[01]D.h, python/BPy_Interface[01]D.cpp: Removed
from the Interface0D and Interface1D C++ classes a back pointer to a
Python wrapper object and all "director" calls. These classes (and
their subclasses) are used to build Freestyle's main data structures
(such as a view map and strokes) and their class hierarchy is static.
Python wrappers of these C++ classes are only used to access the data
structures from the Python layer, and not intended to extend the data
structures by subclassing the Python wrappers. Without the necessity
of subclassing in the Python layer, the back pointer to a wrapping
Python object and "director" calls would be useless (actually they
were not used at all), so they were all removed.
* python/Director.{cpp,h}: Removed the definitions of directors that
were no longer used.
* stroke/Stroke.{cpp,h}: Removed an (unused) back pointer to a Python
wrapper object.
* python/BPy_ViewMap.cpp: Fixed a possible null pointer reference.
* python/Interface1D/BPy_FEdge.cpp: Fixed parameter checking in
FEdge___init__().

propagation up to the toplevel error handler in BPY_txt_do_python_Text().
Before these changes were made, the operator() methods of predicates
and functions, for example, returned a value of various types such as
bool, double and Vec2f. These returned values were not capable to
represent an error state in many cases.
Now the operator() methods always return 0 on normal exit and -1 on
error. The original returned values are stored in the "result" member
variables of the predicate/function classes.
This means that if we have a code fragment like below:
UnaryPredicate1D& pred;
Interface1D& inter;
if (pred(inter)) {
/* do something */
}
then we have to rewrite it as follows:
UnaryPredicate1D& pred;
Interface1D& inter;
if (pred(inter) < 0)
return -1; /* an error in pred() is propagated */
if (pred.result) {
/* do something */
}
Suppose that pred is a user-defined predicate in Python, i.e. the predicate
is likely error-prone (especially when debugging the predicate). The first
code fragment shown above prevents the proper error propagation because
the boolean return value of UnaryPredicate1D::operator() cannot inform the
occurrence of an error to the caller; the second code fragment can.
In addition to the operator() methods of predicates and functions, similar
improvements have been made to all other C++ API functions and methods that
are involved in the execution of user-defined Python code snippets. Changes
in the signatures of functions and methods are summarized as follows (note
that all subclasses of listed classes are also subject to the changes).
Old signatures:
virtual void Iterator::increment();
virtual void Iterator::decrement();
virtual void ChainingIterator::init();
virtual ViewEdge * ChainingIterator::traverse(const AdjacencyIterator &it);
static void Operators::select(UnaryPredicate1D& pred);
static void Operators::chain(ViewEdgeInternal::ViewEdgeIterator& it,
UnaryPredicate1D& pred, UnaryFunction1D_void& modifier);
static void Operators::chain(ViewEdgeInternal::ViewEdgeIterator& it,
UnaryPredicate1D& pred);
static void Operators::bidirectionalChain(ChainingIterator& it,
UnaryPredicate1D& pred);
static void Operators::bidirectionalChain(ChainingIterator& it);
static void Operators::sequentialSplit(UnaryPredicate0D& startingPred,
UnaryPredicate0D& stoppingPred, float sampling = 0);
static void Operators::sequentialSplit(UnaryPredicate0D& pred, float sampling = 0);
static void Operators::recursiveSplit(UnaryFunction0D<double>& func,
UnaryPredicate1D& pred, float sampling = 0);
static void Operators::recursiveSplit(UnaryFunction0D<double>& func,
UnaryPredicate0D& pred0d, UnaryPredicate1D& pred, float sampling = 0);
static void Operators::sort(BinaryPredicate1D& pred);
static void Operators::create(UnaryPredicate1D& pred, vector<StrokeShader*> shaders);
virtual bool UnaryPredicate0D::operator()(Interface0DIterator& it);
virtual bool BinaryPredicate0D::operator()(Interface0D& inter1, Interface0D& inter2);
virtual bool UnaryPredicate1D::operator()(Interface1D& inter);
virtual bool BinaryPredicate1D::operator()(Interface1D& inter1, Interface1D& inter2);
virtual void StrokeShader::shade(Stroke& ioStroke) const;
virtual T UnaryFunction0D::operator()(Interface0DIterator& iter);
virtual T UnaryFunction1D::operator()(Interface1D& inter);
New signatures:
virtual int Iterator::increment();
virtual int Iterator::decrement();
virtual int ChainingIterator::init();
virtual int ChainingIterator::traverse(const AdjacencyIterator &it);
static int Operators::select(UnaryPredicate1D& pred);
static int Operators::chain(ViewEdgeInternal::ViewEdgeIterator& it,

of the original styles are supported: stroke attributes are correctly taken into account, Python shaders are supported. Added SamplingShader.

SShape, ViewShape. Also corrected a few typos (Get#->get#).

Freestyle (on the C++ side). Created the equivalent in Python BPy_Iterator with the simple interface:
- getExactTypeName()
- increment()
- decrement()
- isBegin()
- isEnd()
Contrary to previously stated, I am reverting back to implementing iterators in the (Python) API, for different reasons:
- it will make testing quicker to achieve, as I won't have to recode a big chunk of the original Python files
- it will be a base for API refactoring
- it won't prevent the use a list-based approach later (it is simple to get it from the Iterator)
