It seems that this animation refers to 'PanelInstruments' that is
a panel outside the model, so, when loaded with SGModelLib::load_model
the object is not found in the model and there is a non tested
read access through a null pointer in sgMakeAnimation.
Fix a problem where the compiler would mix up two function declarations because the one wich has SGSubsystem in it's options list expected a const SGSubsystem, but it was called with a plain SGSubsystem
Frederic Bouvier:
This patch is there to correct a problem that prevent to load static objects when specifying a relative fg-root or a different, relative, fg-scenery. It appears that there is a mix between fg-root, fg-scenery and PLIB's model-dir.
It has been reported on the list that users are not able to see the buildings, especially those running the win32 builds because they run 'runfgfs.bat' that set FG_ROOT=./DATA.
I decided not to use model-dir because it just add confusion and to build a valid path earlier.

A patch from Frederic Bouvier which performs z-buffer ordering of the cloud layers to prevent transparency problems with other (se mi) transparent objects. Good work Frederic!

This patch was inspired by Norman. Otherwise there is a segfault on Linux because the global variable tries to access OGL before a valid context is initialized.

Remove "glut" dependency.
- SkyContext.[ch]pp needs to query the window size, but apparently doesn't
do anything with it. We can hard wire a size and the cloud code seems to
behave fine.
- SkyLight.[ch]pp depends on glut_shapes so I copied over the code so it
can access those routines locally. (The routines that are used are
simply combining calls to libGLU.a

Note that SSG and OpenGL use different representations
of Matrices.
1) SSG is row major and OpenGL is column major
2) SSG uses a Z is up whereas conventionally OpenGL uses
Z is pointing into the screen
ie this just requires swapping the Y and the Z axis < columns >
and negating the new Y column
3) Now since SSG eventually calls OpenGL SSG must do this
for us behind the scenes or else things just wouldn't work
so inorder to get Clouds3D to render in the proper location
we should just need to use the Matrix that SSG uses for a Camera
Matrix and pass this directly to the Clouds3D Camers
Jim Wilson:
Fixed texture translation so step and scroll values work with interpolation tables as well. Moved step/scroll calculation to utility function to improve code readability.
Sync he configure script with that one from FLightGear by splitting the LIBS cariable into a base_LIBS, opengl_LIBS, network_LIBS and thread_LIBS variable
Jim Wilson:
This update adds the ability to do multiple texture transforms (Steve B. thinks supporting them at the plib level would be inefficient, which is probably true).
Removed units (e.g. "_m") from texture translation property and variable names since the texture translation values are dimensionless.
Added the ability to specify a scroll factor for stepped texture animation that needs to scroll smoothly when approaching the step interval (e.g. odometer movement).
