bug#45917: [PATCH] Use big brackets in Calc in big mode

[Mattias Engdegård]

The attached patch makes Calc use big brackets in Big mode when the Unicode 
characters are available. This makes for prettier display which is sort of the 
point of using Big mode. It follows previous use of Unicode characters for 
square root and integral signs.

The code supports big versions of round, square and curly brackets. Big square 
brackets are currently only used for intervals and curly ones not at all (maybe 
they could be put to use for Stirling numbers of the second kind).

Matrices do not use big brackets but they probably should since it is standard 
mathematical notation.

As far as I can tell the only reasons for not applying this would be that it is 
common with fonts or terminals where this doesn't look good, or that the 
resulting formula isn't recognised by the embedded-mode parser (which is 
already the case with several other constructs).
