  1. Fonts in Visual DataFlex

    There are many aspects to the discussions about how the new font system in Visual DataFlex works when compared to the old. This is actually a complex topic with a lot of different perspectives so this blog might be on the long side. I promise to do my best not to ramble (too much).
