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.) git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@989 232f8b59-042b-4e1e-8c03-345bb8c30851
