Actually, GeanyWrapLabel is still required with GTK3, because although
GtkLabel is somewhat supposed to do it, it actually doesn't.  You can
make it wrap dynamically by setting the character-width property, but
that won't event really do what you want, apparently the label will
still request the minimal size for it to display when wrapped at that
size, and then will be too tall if wrapper to something larger.

That's not really "broken", it's just a bunch of labels.  But yeah we
could make those selectable if we wanted.

I fixed something in the about dialog header with GTK 3.8+, that might
have been the cause of the CPU usage you saw.  On Linux it used to eat
some CPU, and emit tons of warnings (probably like 1 each 4 clock tick,
which is probably like 15 a second).
