Dear Hans and others, I'm usually use the \big, \Big, \bigg etc to get the size of parentheses, brackets and braces to be the size I want. I realize that the fences machinery is probably a cleaner way of doing this.
I tried it a bit, and it usually gives the result I like. But sometimes
not, and it seems that the way to change the size of the
parentheses/brackets/braces is to use the factor key.
1) Are the different options none, auto NUMBER explained somehere?
2) Could one have, for exceptional cases where the default is not
satisfactory, a keyword like factor=big for example, to get the same size
as if one would have used \big?
I am a bit confused. See the example below, with output (from latest
standalone) attached.

PS: I would suggest to have
italic = { feature = 'ss01', value = 1, comment = "Mathematical
Alternative Lowercase Italic" },
set in lucida-opentype-math.lfg. In all books (on math) I have seen, I
think this is what is used.
