FIX: Minor text tweaks

@almarklein ready for review/merge, just minor tweaks on your changes.
Not sure I agree with this.. "size" is a bit ambiguous. Currently there is not a way to ask about the size of the area occupied by the text, or to specify the maximum size of that area. When these are added, might there be confusion about which "size" this refers to? A while back, we had also discussed the possibility of adopting SVG terminology as much as possible..
