-AppleSGLX Release Notes
-
-o OpenGL Support
-
-AppleSGLX supports the same version of OpenGL as Leopard (OpenGL 2.1).
-Many extensions from the OpenGL framework are now builtin.
-
-This adds support for GLSL, and a variety of other features.
-
-o Thread Support
-
-Thread support has been improved since the libGL in XQuartz 2.3.2.1.
-
-o GLX 1.4 Support
-
-The GLX 1.3 and 1.4 functions should all work with a few exceptions
-as outlined in this document.
-
-o glXMakeContextCurrent (a GLX 1.3 feature)
-
-glXMakeContextCurrent should work with the readable drawable. The
-OpenGL functions: glReadPixels, glCopyPixels, and glCopyColorTable,
-should use the readable drawable if it's different than the rendering
-drawable.
-
-o glXGetProcAddress (a GLX 1.4 feature and ARB extension)
-
-glXGetProcAddress should work and allow getting the address of any
-extension functions you may need from the X11 libGL, or OpenGL framework
-libGL. Previous versions of the X11 libGL didn't allow getting the newer
-OpenGL framework addresses.
-
-o GLXPixmaps
-
-New support for GLXPixmaps works well with mixed X11 and OpenGL drawing
-operations. You can create them using glXCreateGLXPixmap or
-glXCreatePixmap.
-
-o GLXPbuffers
-
-Support for GLXPbuffers has been added. These are drawables that are
-not possible to render to with X11, which is allowed by the spec.
-A GLXPbuffer will never generate a clobber event, however
-glXSelectEvent and glXGetSelectedEvent should operate normally.
-
-Clobber events are not generated due to low-level architectural
-differences. The contents of your pbuffers will not be clobbered.
-
-o Shared Contexts
-
-Due to basic low-level architectural differences the usage of shared
-contexts requires a similar visual or GLXFBConfig be used in the
-creation of a shared context. It's best if you specify the same
-visual. This is due to a CGL design difference, and not something
-that is easily worked around. UPDATE: some changes made seem to
-help resolve this issue in many cases, so you may be able to use a
-shared context without this restriction.
-
-
-o Indirect
-
-The X server supports indirect fairly well, so OpenGL applications
-can be run remotely and displayed by XQuartz. This means you can run
-applications from a remote host on an XQuartz X server.
-
-AppleSGLX does not support indirect rendering. Any indirect context
-created will appear to glXIsDirect as an indirect context, but it
-does not actually support indirect rendering to a remote X server.
-
-AppleSGLX supports GLXPixmaps and GLXPbuffers with direct and indirect
-contexts, though they are all direct contexts by definition (see above).
