Generating 9pt FreeFonts versus Adafruit_GFX 9pt versions

[prenticedavid]

Regular style has many missing pixels
Bold style is readable but less attractive than the Adafruit versions.

I expected problems with 6pt and 7pt fonts. But obviously Adafruit must have scaled the 9pt well.
I presume that your algorithm creates anti-aliased result which is converted to a final monochrome font.

An online tool is much more convenient than attempting to build tools on a Windows platform.
