X8R8G8B8, A8B8G8R8, X8B8G8R8, A2R10G10B10, A2B10G10R10, L4A4 (not work

Q16W16V16U16, R32F, R16F and A32B32G32R32F.
And these ones are correctly detected, but prints "unsupported" using
osg::notify(osg::WARN) and are not loaded:
A8R3G3B2, G16R16, G16R16F, G32R32F and CxV8U8.
Also added checking of not supported DDPF_BUMPDUDV (V8U8, V16U16,
Q8W8U8L8, A2W10U10V10 etc.) and DDPF_BUMPLUMINANCE (L6V5U5, X8L8V8U8,
etc.) pixel formats.
Mipmap handling is slightly modified and now support all additional formats.

changes I made:
+ put a warning in the console if a nonexistant screen is requested
+ add getters for the aglcontext and pixelformat -- I need access to
them in my own code.

old loader, but appear very, very wrong with the new one. I traced the
problem to the handling of the palette override flags in the external
reference records. The current behavior for handling the palette
override flags for external references has different offsets for
different OpenFlight version (2 bytes for 14.2-15.1 and 4 bytes for 15.2
and later). However, I believe this behavior is incorrect.
I know that the original 14.2 OpenFlight spec (dated April 1995)
specifies 2 bytes between the filename and the override flags, and the
15.4 and later specs specify 4 bytes. However, I also found a 14.2.4
OpenFlight spec (dated January 1996) that changes the specification to 4
bytes. Also, the databases in question were created using an old IRIX
version of MultiGen II, which wrote OpenFlight 14.2 files natively.
These files also have 4 bytes between the filename and flags.
Furthermore, these databases have always worked properly under earlier
versions of OSG, under Performer, and in every MultiGen product we've used.
This leads me to believe that the original 14.2 spec was incorrect (the
14.2.4 spec corrected this error), and there should be 4 bytes between
the filename and flags for all OpenFlight files version 14.2 and later.
The attached fix modifies the OpenFlight loader to behave in this way."
Currently, if the texture attribute file doesn't explicitly specify an
internal format, the loader will force it to use GL_RGB, which keeps
translucent textures (eg. GL_RGBA textures) from showing up properly.
This patch changes the default behavior to simply use the image's format
instead of forcing a particular format."
libraries listed under TARGET_EXTERNAL_LIBRARIES.
The removed libraries are not needed when linking the plugin, they are
loaded during runtime by Performer.

that the terrain is always the Earth planet. I changed the constructor
method to accept the Equator radius and the Polar radius like
parameters. By default, it assumes the Earth radius for the
EllipsoidLocator. I added a setEllipsoidModel method, too.
Now, we are developing some libraries for a GIS applicacion, and our
libraries can visualize terrains of planets like Mars. I think that is
a interesting change."
I added _preDrawCallback member and neccessary access methods plus modified osgUtil RenderStage.cpp to invoke it before all drawInner calls are made. I tried to maintain symmetry with postDrawCallback but you know better where is a proper place for this call ;-)

window.
The win32 implementation is still in its original shape since I have no win32
implementation available.
I have chosen the enum approach for the first cut. That is benefitial since
the user does not need to track creation of mouse cursors for different
windows and displays in presence of multiple viewer windows.
The default set of available mouse shapes is the same set that was available
with glut. That set served many OpenGL applications well, so the hope is that
this is enough.
Even though, that implementation is still extensible:
I have digged out the way SDL defines new mouse cursors and added a still
documented out function prototype in the GraphicsWindow that can be used to
extend the current implemtation for arbitrary mouse shapes. That is not
implemented yet.
I hope that somebody with a win32 test system can catch up that implementation
on win32."
