* #aiGetMaterialTextureCount() can be used to determine the number of
* textures in a particular texture stack.
* @param[out] path Receives the output path
* If the texture is embedded, receives a '*' followed by the id of
* the texture (for the textures stored in the corresponding scene) which
* can be converted to an int using a function like atoi.
* This parameter must be non-null.
* @param mapping The texture mapping mode to be used.
* Pass NULL if you're not interested in this information.
* @param[out] uvindex For UV-mapped textures: receives the index of the UV
* source channel. Unmodified otherwise.
* Pass NULL if you're not interested in this information.
* @param[out] blend Receives the blend factor for the texture
* Pass NULL if you're not interested in this information.
* @param[out] op Receives the texture blend operation to be perform between
* this texture and the previous texture.
* Pass NULL if you're not interested in this information.
* @param[out] mapmode Receives the mapping modes to be used for the texture.
* Pass NULL if you're not interested in this information. Otherwise,
* pass a pointer to an array of two aiTextureMapMode's (one for each
* axis, UV order).
* @param[out] flags Receives the the texture flags.
* @return AI_SUCCESS on success, otherwise something else. Have fun.*/
