When I was writing the demo, I realised it would be handy if I could arbitrarily remove strings as well as add them - completely remove them from the whole system.
The FontManage controls the texts - it has an internal list of them. So if you remove a text from the view say, it will still physically be there, creating resources. It's really needed for transient displays, so suppose you pop up a screen over a game displaying some information and want to use a bitmapped font, then you can create bitmap strings on entry and remove them on exit.
None of this should affect any prior written code in any way.
