Can you be more specific?  The default editor config does have integration
with FMath which allows users to create complex equations via a GUI.  The
end result is an image.

The chart is correct.  There has never been good browser support for MathML
rendering in the browser.

The FMath editor creates images because browsers have offered such lousy
support for MathML.

The CKEditor config is easy to modify in a single JS file
(ckeditor.launch.js).  Institutions continue to be free to modify the
default config and use other editors like the completely Javascript-based
editor from WIRIS (http://www.wiris.com/en/).  We felt that including a
free editor by default that produces images made the Sakai default build
better.
