When the font size gets to a certain size (at some point after 1200 pixels), DirectWrite will just return an empty rect as the bound for it and does not want to render it. At this point, you might want to consider other ways of rendering the text, but since the same did not happen e.g. with the Freetype backend, it was an unfortunate platform difference. As a fail safe, we detect when this occurs and fall back to the QFontEngine base class approach of drawing the glyph as a QPainterPath instead. [ChangeLog][Windows] Fixed an issue where glyphs might be missing for very large fonts.
