Ehsan Akhgari 8c296bbcd4 Bug 579517 - Part 1: Automated conversion of NSPR numeric types to stdint types in Gecko; r=bsmedberg
This patch was generated by a script.  Here's the source of the script for
future reference:

echo "Converting $1 to $2..."

// <mfrac> -- form a fraction from two subexpressions
//
/*
The MathML REC describes:
The <mfrac> element is used for fractions. It can also be used to mark up
fraction-like objects such as binomial coefficients and Legendre symbols.
The syntax for <mfrac> is:
<mfrac> numerator denominator </mfrac>
Attributes of <mfrac>:
Name values default
linethickness number [ v-unit ] | thin | medium | thick 1
E.g.,
linethickness=2 actually means that linethickness=2*DEFAULT_THICKNESS
(DEFAULT_THICKNESS is not specified by MathML, see below.)
The linethickness attribute indicates the thickness of the horizontal
"fraction bar", or "rule", typically used to render fractions. A fraction
with linethickness="0" renders without the bar, and might be used within
binomial coefficients. A linethickness greater than one might be used with
nested fractions.
In general, the value of linethickness can be a number, as a multiplier
of the default thickness of the fraction bar (the default thickness is
not specified by MathML), or a number with a unit of vertical length (see
Section 2.3.3), or one of the keywords medium (same as 1), thin (thinner
than 1, otherwise up to the renderer), or thick (thicker than 1, otherwise
up to the renderer).
The <mfrac> element sets displaystyle to "false", or if it was already
false increments scriptlevel by 1, within numerator and denominator.
These attributes are inherited by every element from its rendering
environment, but can be set explicitly only on the <mstyle>
element.
