There are two sets of getters there; and the non-const ones may copy the COW mpImplFont, and may call its AskConfig. The name overload is unfortunate. It is not obvious at the call site, which of the two will be called; and what is different. IMO, the way to fix it would be to keep only one set of getters (the const one), and make the call to AskConfig explicit (in the places that set font name, and know that resolution of other properties will be needed). But in this change, I only rename the non-const getters, making sure to keep the behavior unchanged (at least the intention is to have a non-functional change, meaning that the places that called non-const overload, now use the renamed functions), to make it clear where we actually may copy and initialize it.
