[ remainder omitted ]

Then let me correct that omission right now. I appreciate these graphics drivers very much, especially the PNG driver that I now use routinely for placing R-generated graphics into so-called "presentation" software such as Microsoft PowerPoint.

I remember very well how inconvenient I used to find it to transfer graphics into such documents, i.e., those of both MS Word and MS PowerPoint. Not so any longer.

Thank you,
