the strings used in materials and elsewhere in assimp. Because of this,
in PyAssimp3 strings in materials don't work properly on 64 bits
platforms. This commit adds a StringUInt32 ctypes structure and use it
in GetMaterialProperties as a workaround.

PyAssimp3 Readme
---------------
-- a simple Python3 wrapper for Assimp using ctypes to access
the library. Works with Python 3 upwards.
Note that pyassimp is by no means considered mature. It works,
but it is far away from wrapping Assimp perfectly.
USAGE
=====
To get started with pyAssimp, examine the sample.py script, which
illustrates the basic usage. All Assimp data structures are
wrapped using ctypes. All the data+length fields in Assimp's
data structures (such as 'aiMesh::mNumVertices','aiMesh::mVertices')
are replaced by simple python lists, so you can call len() on
them to get their respective size and access members using
[].
For example, to load a file named 'hello.3ds' and print the first
vertex of the first mesh, you would do (proper error handling
substituted by assertions ...):
> from pyassimp import pyassimp, errors
>
> try:
> scene = pyassimp.load('hello.3ds')
> except AssimpError, msg:
> print(msg)
> return
> assert len(scene.meshes)
> mesh = scene.meshes[0]
> assert len(mesh.vertices)
> print(mesh.vertices[0])
> # don't forget this one, or you will leak!
> pyassimp.release(scene)
INSTALL
=======
PyAssimp requires a assimp dynamic library (DLL on windows,
so on linux :-) in order to work. The default search directories
are:
- the current directory
- on linux additionally: /usr/local/lib
To build that library, refer to the Assimp master INSTALL
instructions. To look in more places, edit ./pyassimp/helper.py.
There's an 'additional_dirs' list waiting for your entries.
