I wouldn't expect the results of a rasterized string necessarily be the
same as a tiling of the individually rasterized glyphs. That is because
there are issues like kerning and ligatures which might come into play
(if supported and enabled). That's why rasterizing a string can't be
implemented simply by mapping the glyph bitmaps, even though a primitive
implementation might fall back to that.
