Details:

There are a couple of bug reports (that partly overlap) that show the need for
(complete?) rewrite of legend.m: 
* bug #49940, bug #41142: related to the fact that legend deletes and
recreates text objects when someone tries to change a single text property on
the object directly
* bug #39697, bug #39316: related to the legend object not having listeners on
the figure/axes position so that it doesn't behave well when the figure or
axes rescaled
* bug #47455: building a legend is slow, updating it is also very slow since
most of the time the legend is entirely rebuilt.
* bug #40333: changing the fontsize on a legend modifies its corresponding
axes position, if the latter position has changed since the legend was
created
