Hi Andreas,

I just noticed your checkins from last night. It seems that the triangle mesh
is progressing, that's good to know!

I tried to compile the code on Linux, and have a few comments:

- I would love to remove the configure test for endianness and replace it with
   a class like you did, but unfortunately this breaks the binary stream classes
   (kernel/bstream.h) in the respect that you can no longer write
     bistream<file_is_lsb> inputfile("foo.bin");
   This only works if "file_is_lsb" is a compile-time constant, and this can only
   be done as long as we use a configure mechanism.
   If we could do it via expression templates (like we do with the datatypes) that
   would work, but I don't know how to do that.
- In trianglemesh.cxx a function filelength() is called, which does not exist
   on Linux. We will have to find something more portable.
- TRIANGLE_MESH::All_Intersections() appears to return only the first intersection
   with the mesh.


TRIANGLE_MESH::Load3DS() might be a good candidate for using the bistream class.
(I expect that the 3DS files are always little-endian, so they have to be swapped
on a big-endian machine).

Cheers,
   Martin
