Fixed Issue 213: Expose GLCaps from GLDrawable
Added getChosenGLCapabilities() to the GLDrawable interface.
Implemented on Windows, Unix and Mac OS X platforms with various
techniques. Attempts to provide correct answers in all cases, even
when the GLCapabilitiesChooser mechanism is not supported. Required
addition of new platform-specific Java code in most cases to either
re-convert existing PIXELFORMATDESCRIPTORS / XVisualInfos, or to query
the pixel format or visual chosen for drawables like pbuffers for
which the chooser mechanism is not (yet) implemented. Tested on
Windows, Solaris/x86, and Mac OS X with on-screen, off-screen and
pbuffer drawables. (Full support for the Java2D/JOGL bridge is not yet
in place; the answer returned from the GLJPanel in this case is
currently the default GLCapabilities, and it is likely that "external"
GLDrawables will return null.)
