timoore c7dab4abea rewrite of sky dome code
Add more points to the dome, giving it a dome shape rather than a
dunce cap shape.

Represent as OpenGL DrawElements instead of as triangle strips.

Only calculate have the sky colors and reflect those across the dome.

timoore 600726976c Add methods to SGGeod to return OSG Matrix objects for local frames.
Methods have been added for Z down (simulation) and Z up frames.

	system. Move the implementation into SGGeodesy.cxx. Remove some of
	the old Point3D Based sg* functions that are already unused.

mfranz 9567ac32f2 remove obsolete files (on request by Christian Mayer, who has introduced them):
- they are not used anywhere in sg/fgfs
- and are very clearly *not* GPL compatible!

ehofman 75f817b39c Mathias Fröhlich:
The patch adds a vector lib I have put together during the last time,
it is just handy and interfaces well with s(s)g*. Together with some small
modifications this will later also interface well with OpenSceneGraphs
vectors/matrices. Using this vector kernel is targeted to have a handy
matrix/vector lib available and to provide a scenegraph independent vector
type for use with a small scenegraph wrapper aimed for a smooth transition to
openscenegraph.

That vector code also includes an improoved geodetic conversion routine I
have found some time ago published in the 'journal of geodesy' which avoids
iterative computations for that purpose.

Also the geodetic position class is more typesafe and unitsafe than the
Point3D currently is.

That part is relatively old and in use in my local trees for several months
now.

curt a885314a39 Tidy up the autoconf/automake configuration a bit.
- Removed some old cruft.

- Removed some support for older versions of automake which technically was
  correct, but caused the newer automakes to squawk warnings during an
  initial sanity check (which isn't done very intelligently.)

  NOTE: this fix is technically not correct for older version of automake.
  These older version use the variable "INCLUDES" internally and could have
  them already set to an important value.  That is why we were appending
  our values to them.  However, newer versions of automake don't set this
  value themselves so it is an error to append to a non-existant variable.
  We seem to "get away" with overwriting the value on older versions of
  automake, but if you have problems, consider upgrading to at least
  automake-1.5.

curt 220a43bf46 Removed metakit and zlib from the configure/build process. The
developer will need to build and install these separately if they don't
have packages already installed by their system.  See README.metakit and
README.zlib for more details.

As a convenience, pristine tarballs of the metakit and zlib source code
trees are included with the simgear distribution (and cvs.)

curt 5bab565cfe Updates to build system to better support automake-1.5
- automake-1.4 sets default values for INCLUDES which we can't
  overwrite.
- automake-1.5 renames this to DEFAULT_INCLUDES and leaves INCLUDES
  open for the developer to use.

Thus for automake-1.4 we are forced to 'append' to INCLUDES and in
automake-1.5 we can just set the value to whatever we like.
Unfortunately, the behaviors of the two versions are mutually
incompatible.

The solution I am committing now works for both versions but
automake-1.5 generates a lot of spurious warning messages that are
annoying, but not fatal.
