At the moment if you call font.CharSize( x) the glyph list is destroyed and
rebuilt, which will be really inefficient if you change sizes often. Will
the freetype cache stuff help here or should we cache internally?

+multiple glyphlists. glyphlist manager. FTSize obj???
When is the best time to construct the glyphList? After the call to Size(x)
is the earliest but what happens if the client doesn't set the char size?
The FTSize seems redundant.
+Need a way to restrict the glyphs to a custom set. eg an app only needs
+numbers so we should only create a glyphList of the number characters.
+This will enable us to have a restricted set of HIGH quality glyphs.
