Largest size of radical symbol does not connect to beam (STIX fonts only)

[GoogleCodeExporter]

What steps will reproduce the problem?

$\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+x}}}}}}}$

(#13 in the MathML torture tests)

What is the expected output? What do you see instead?

The radical sign (checkmark) should be connected to the stem even in the
very largest size.

This is likely a bug in the font metrics of the STIX fonts.

It appears as if the largest size radical is the equiv of TeX's variable sized
delimiters which use one or more intermediate elements (vertical bars) to 
produce
\sqrt signs of any height.

That would explain why the line is vertical, rather than angled. It would also
explain why it is so much larger than the other radical signs (not meant to be 
scaled
to large heights). The gap is explained by there being a small 'L' shaped 
connecting
symbol.

Currently no such support for this type of symbol in Mathtex. Fix applied in 
r89..
