(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.

/*! Base class for Stroke Shaders.
|
|
* Any Stroke Shader must inherit from this class and overload the shade() method.
|
|
* A StrokeShader is designed to modify any Stroke's attribute such as Thickness, Color,
|
|
* Geometry, Texture, Blending mode...
|
|
* The basic way to achieve this operation consists in iterating over the StrokeVertices of the Stroke
|
|
* and to modify each one's StrokeAttribute.
|
|
* Here is a python code example of such an iteration:
|
|
* \code
|
|
* it = ioStroke.strokeVerticesBegin()
|
|
* while not it.isEnd():
|
|
* att = it.getObject().attribute()
|
|
* ## perform here any attribute modification
|
|
* it.increment()
|
|
* \endcode
|
|
* Here is a C++ code example of such an iteration:
|
|
* \code
|
|
* for (StrokeInternal::StrokeVertexIterator v = ioStroke.strokeVerticesBegin(), vend = ioStroke.strokeVerticesEnd();
|
|
* v != vend;
|
|
* ++v)
|
|
* {
|
|
* StrokeAttribute& att = v->attribute();
|
|
* // perform any attribute modification here...
|
|
* }
|
|
* \endcode
