especially for 3D textures, tileable noise images take some time to create.

as there are no image types with support for 3D images, the 'filename'-parameter can be used to write the image to a file. if the string is empty, no file is written. the written image format is a 3D-version of the pgm-format (portable greyscale map), so there is no compression (file's size is (width*height*depth bytes + a few bytes of header-information) only 8-bit color-values are supported for reading and writing creates a 3d noise texture the 'filename' parameter cannot be used to read a file. existing files are overwritten.
