def import3ds(filename):
"""Import a 3DS file into the current scene of Blender.
Usage:
import3ds(filename)
Implementation notes:
1. Must be run from within Blender, of course.
2. It does not handle smoothing data at all: output is all solid.
3. If a texture cannot be found, it does a case-insensitive search
of the directory; useful on case-sensitive systems when reading
a 3DS file made on a case-insensitive systems by some ignorant
fellow.
4. If a texture is not in PNG or JPEG format, it saves a copy of
the texture as a PNG file in the same directory. Blender uses
the copy for the texture, since Blender only understands JPEG
and PNG. Useful for when said ignorant fellow uses a BMP file.
