implementations on all platforms have been split into orthogonal
GLDrawable and GLContext concepts. It is now possible to create more
than one GLContet per GLDrawable (though this has not been tested
yet). GLCanvas has been reimplemented in terms of
GLDrawableFactory.getGLDrawable(). More functionality has been moved
from GLDrawable to GLAutoDrawable. Reimplemented lazy sending of
reshape GLEventListener events in GLCanvas and GLJPanel and deleted
notion of deferred reshapes from GLDrawableHelper and elsewhere.
Sharing of textures and display lists is now expressed in terms of
GLContexts instead of GLDrawables. Still need to move pbuffer creation
into GLDrawableFactory from the onscreen GLContext implementations.
Added option to gleem ExaminerViewer to disable automatic redraws upon
mouse events and respecified more of gleem to work on GLAutoDrawables
rather than GLDrawables. Updated all JOGL demos to work with new APIs
and slightly different initialization sequences (in particular, for
pbuffers -- this will change with the addition of
GLDrawableFactory.createGLPbuffer()).

has been exposed in the public API. The GLEventListener callback
mechanism has been removed from the core GLContext implementation and
moved up to a higher level. GLAutoDrawable now contains the
GLEventListener-related methods, and the GLEventListener's methods now
receive a GLAutoDrawable as argument. All JOGL demos have been updated
for the new APIs. Many FIXMEs and much unimplemented functionality
remain. There is slightly different initialization behavior for the
demos containing pbuffers, and the deferring of reshape callbacks
needs to be rethought.

users in JOGL 1.1 betas where the code path for
wglChoosePixelFormatARB (supporting full-scene antialiasing) was
failing on older cards. The old drivers expect an OpenGL context to be
current while the wglChoosePixelFormatARB and associated calls are
being made, even though the documentation explicitly states that this
is not necessary. GKW's fix creates a native window synchronously
(independent of the AWT) and associates an OpenGL context with it
which is used to choose pixel formats for other windows on the same
GraphicsDevice. Upon VM shutdown, a native message pump is started
which causes proper disposal of the native window and its OpenGL
contexts.
There is currently no bug ID associated with this fix, although it may
be a component of completely addressing several open bugs.
Also includes a bug fix from GKW and kbr for:
Issue 98: Just 1st frame rendering on ATI Radeon
This was a race condition between JOGL's automatic discovery that the
ATI_WORKAROUND was needed and the creation of the first GLCanvas and
associated Animator. The need for disabling the setRenderingThread
optimization was computed too late, incorrectly locking out other
threads (in particular, the AWT event queue thread) from performing
rendering of the component.

Issue 59: GLContext Leak
Issue 67: Java/Jogl app hangs some systems, not others, during reshape.
Issue 69: Error on window resize
Issue 89: Losing Backbuffer when Resizing/Moving a window
The primary change is to support handing off of the display()
implementation to the AWT event queue thread via a new class called
SingleThreadedWorkaround in the impl package. This was done to cause
the AWT's reshape code to execute on the same thread as all other
OpenGL rendering without changing the threading model (e.g., Animator
and the ability to manually call display()) visible to the end user.
This set of changes appears to work around the problems seen on ATI
cards with random corruption when resizing animating windows due to
multithreading bugs in the drivers. More testing by a larger community
will confirm this fix. Currently the workaround is enabled by default
on ATI cards.
A secondary but related change is to properly destroy the OpenGL
context when a heavyweight component is removed from its container.
In order to implement the above workaround, it was necessary to
override addNotify and removeNotify to properly track whether
GLCanvases were realized; at that point it was a fairly small step to
properly delete and recreate OpenGL contexts. The previous heuristics
which attempted to determine when a heavyweight had been realized have
been removed. A new demo, TestContextDestruction, exercises the new
functionality. It does still appear to exhibit resource leaks,
however; removing and re-adding the GLCanvas from its parent multiple
times causes the system to eventually slow down significantly. More
work is needed in this area. However, the demo does now execute as
opposed to throwing an exception which was the previous behavior.
The current code has been tested on Windows on NVidia hardware with
all existing demos with the workaround both enabled and disabled, and
on ATI hardware with the existing compatible demos with the workaround
enabled. The new abstract method in GLContext, destroyImpl(), has been
implemented but not yet tested on X11 and Mac OS X.

was thrown during init(). Fixed build.xml files to get javac to
produce source file and line number information. Fixed demos to pop up
a dialog box if an extension they need is unsupported.
