Graphs: labels keep paragraph settings and anti-aliasing when the graph is drawn again

Paragraph settings given to all of a graph label's text with
text.setFormat (indents, spacing, hyphenation, Justification options,
composer, direction, kashida, kinsoku, mojikumi, burasagari and the
rest) and the label's anti-aliasing method were lost when the graph
drew its labels again, because the graph kept only a character style
for each kind of label. Each kind now also keeps its paragraph settings
and anti-aliasing method, saved with the graph in its label styles, and
the graph still sets each label's alignment for its place.

The legend spaces its entries by the kept legend settings: Legend
Across Top measures each label with its indents and spacing, both
legend layouts make room for extra leading or paragraph spacing, and a
label with a negative indent or negative space before moves right or
down so it stays clear of its swatch and of the entry above it.
