Rendering issues due to font-hinting

[bbc131]

Because of font-hinting, icons sometimes are rendered not very nice.

See the two screenshots below, the left screenshot is the default situation, whereas for the right screenshot I disabled font-hinting
It shows four different icons in a toolbar and pushbuttons.

The extend of the problem and its visual appearance varies with the kind of icon and its size.
In my mwe for example,

• the distance between the bars of the fa5s.bars icon appear not equally in both versions,
• the bottom bar of mdi6.menu for the toolbar size is considerably thinner than the other two bars and
• the fa5.plus-square in the pushbutton is not really appealing.

All those issues are definitely mitigated with font-hinting disabled, as you can see in the right screenshot.

I saw #203 and do wonder why this isn't set by default, but only for animations?

I think, at least, this would be worth an option.

I created this on Windows 11 with PySide6.

Hi @bbc131 thank you for the feedback and sorry for such a late response! From the comparison above seems like having a font_hinting option could make sense 👍 Maybe we need to check if the same happens with other bindings/bindings versions to check what default value could be better 🤔

If you are interested in implementing the option let us know!

Edit: Also, just in case, what do you think @ccordoba12 ?

I think this a great tip and we should definitely check it to see if the icons display can be improved by disabling font hinting.
