Removed all references of deprecated texture shader. Also deleted
several lines of dead code.
Since texture_shader.py no longer does what it was supposed to do,
the file itself was removed.
Patch reviewed by Tamito Kajiyama (kjym3).
structure.
Additional bug fixes were also done along with the code updates:
* Fix for the use of old Interface1D.pointsBegin() and .pointsEnd() method names
in the definition of pyDensityAnisotropyF1D and pyViewMapGradientNormF1D.
* Fix for wrong data types (int instead of bool) for:
- pyChainSilhouetteGenericIterator constructor and its .orientation property in
modules/freestyle/chainingiterators.py.
- SpatialNoiseShader constructor in styles/external_contour_sketchy.py.
- ChainSilhouetteIterator constructor in styles/multiple_parameterization.py.
Both C- and Python-coded API components were rearranged into logical groups.
New Python modules are packaged as follows:
freestyle - Top-level package
freestyle.types - Classes for core data structues (e.g., view map)
freestyle.chainingiterators - Pre-defined chaining iterators
freestyle.functions - Pre-defined 0D and 1D functions
freestyle.predicates - Pre-defined 0D and 1D predicates
freestyle.shaders - Pre-defined stroke shaders
freestyle.utils - Utility functions
The Python modules are installed in scripts/freestyle/modules. Pre-defined
styles are installed in scripts/freestyle/styles.
To-do: update styles according to the new Freestyle API package structure.
