"""
Material creation takes nontrivial time on large models.
So we cache them aggressively.
However, in Blender, texture is a part of material, while in
X3D it's not. Blender's notion of material corresponds to
X3D's notion of appearance.
TextureTransform is not a part of material (at least
not in the current implementation).
USE on an Appearance node and USE on a Material node
call for different approaches.
Tools generate repeating, idential material definitions.
Can't rely on USE alone. Repeating texture definitions
are entirely possible, too.
Vertex coloring is not a part of appearance, but Blender
has a material flag for it. However, if a mesh has no vertex
color layer, setting use_vertex_color_paint to true has no
effect. So it's fine to reuse the same material for meshes
with vertex colors and for ones without.
It's probably an abuse of Blender of some level.
So here's the caching structure:
For USE on apprearance, we store the material object
in the appearance node.
For USE on texture, we store the image object in the tex node.
For USE on material with no texture, we store the material object
in the material node.
Also, we store textures by description in texture_cache.
Also, we store materials by (material desc, texture desc)
in material_cache.
