Make the integral U+222B stretchable to an arbitrary size #68

Closed davidmjones closed 6 years ago

Although the default in LaTeX and MathML is to use a bigger variant for "displaystyle" integral, some people may want to stretch the integral to an arbitrary size. There are pieces for that in Unicode. Here is what is used in Gecko:

The Unicode componenents are 0x2321, 0x23AE and 0x2320. But they are absent in STIX1.1.1

After more testing, the components are present but are not properly mapped. So here what should be done to stay backward compatible:

Make U+2321 use the glyph "uni2321.s1"
Make U+23AE use the glyph "uni23AE.s1"
Make U+2320 use the glyph "uni2320.s1"
Make U+222B stretchable to an arbitrary size by using the components "uni2321.s1", "uni23AE.s1" (extender) and "uni2320.s1".
