Face description should state ALL its metrics and its glyph metrics are scaled after set-char-size() is called

I've mentioned that glyph metrics are scaled and added some code to illustrate this to doco for the set-char-size method.

I also fixed the kerning method to not divided by 64 when mode is FT_KERNING_UNSCALED, so FontFreeType 0.4.9 is needed to work as documented.

Much better, David. But just to be clear, are the kern metrics scaled when using 'set-char-size'?

Is there a reason the face metrics can't be scaled at the same time as the glyphs are when using 'set-char-size'?

You might mention that only the width need be entered to 'set-char-size' and the height will be the same.

Please see Font::FreeType release 0.50

Rather than changing set-char-size(), which could have an impact, I've added a set-font-size() method that scales both the glyph and font metrics.

set-char-size() is now documented as being an 'older alternative' to set-font-size().

That's great, David, and I'm converting my code now.

However, in the Changes file, I see that it's new and replaces something, but I don't see that it mentions specifically what it replaces.

Also, in the Face.rakumod file, the pod for set-font-size doesn't mention it also scales the base font metrics, i.e., that it replaces and augments the deprecated set-char-size method.

I have v0.5.0 installed and see .underline-thickness but not .underline-distance.

[dwarring]

Hi Tom, there is an .underline-position

"Ouch," he said, slapping his forehead, "I didn't see that, or I was focused on distance."

Thanks, David, sorry for the bandwidth waste. I only wish I could blame it on old age!
