Subject: Large mathematical operators: summation, product, and integral.
X-Git-Tag: bedstead-002.000~61
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~bjharris/git?a=commitdiff_plain;h=c9d168e2345b68dad9508eda8cd673840d18eb5b;p=bedstead.git

Large mathematical operators: summation, product, and integral.

All of these span the full height of the character cell, since that way
they'll work equally badly with subscripts and superscripts.
