is not the usual OpenGL BOTTOM_LEFT orientation, but with the origin TOP_LEFT. This
allows geometry setup code to flip the t tex coord to render the movie the correct way up.
bugs in the Carbon-implementation of GraphicsWindow, so here's another
fix for setWindowDecorationImplementation, now updates the
titlebar-height, and fixes some display-issues when switching the
decoration on/off.

Stephan: "attached you'll find some modifications to the GraphicsWindow-class and
their platform-dependant implementations.
The problem:
setWindowRectangle and setWindowDecoration do not update the
traits-object, so, if you call setWindowRectangle on a
not-realized-window it will open with another size when realized later.
getWindowRectangle reports possible wrong sizes if setWindowRectangle
called before.
My solution:
split the implementation in two parts:
GraphicsWindow::setWindowRectangle will update its traits-object and
call afterwards the virtual method setWindowRectangleImplementation
(which is implemented by the derived platformspecific classess). For
setWindowDecoration I am useing a similar mechanism.
I hope you'll find the submission useful, the Win32 and X11 changes are
not tested but should work."
Changes to this made by Robert are call of resized in setWindowRectangle
instead of setting of Traits, and use of a bool return type.
R3G3B2, R5G6B5, A1R5G5B5, X1R5G5B5, A4R4G4B4, X4R4G4B4, R8G8B8 (now
without swaping of red and blue), A8R8G8B8 (also w/o swapping),
X8R8G8B8, A8B8G8R8, X8B8G8R8, A2R10G10B10, A2B10G10R10, L4A4 (not work
on my machine), L16A16, L16, A16B16G16R16, A16B16G16R16F,
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."
