Re: Custom CellRendererText doesn't update cell size

Do you really have to override snapshot_vfunc() and call it explicitly? 
Isn't gtk's internal version good enough and called when you set 
property_text()? The CellrendererText will expand as necessary only if 
it's inserted in a container widget that allows it to expand.
