Thanks for tracking this issue down @bforlgreen! It's amazing how less than a pixel of spacing can drive you nuts once you realize it's there 🤪 |

I noticed that the font spacing between characters was not consistent. This resulted in spacing between characters that almost looks like white space, as can be seen in the image below :
To correct this, there is a property on the skia Paint object that enables subpixel text rendering. Enabling this results in much more consistent spacing between characters.
In the image below, the lines with the '!' at the end have
SubpixelTextset to true.It's very subtle, but notice how they have a consistent 1 pixel gap between the characters?
Where as the ones below (without the '!', with
SubpixelTextset to false) have either a 2 pixel gap, 1 pixel gap or no pixel gap.The cookbook example now also looks better
I have added this property to the
Labelclass with the default being set to true.
