Rich Text Support

[Pedro Duque Vieira]

I agree.

A UI framework needs at least a standard set of controls in its core. I'd
say at least 90% of UI apps being created need at least a couple of UI
controls.

I think we should focus on having a strong core library that would allow to
build additional controls, by at least third parties. Things like
FontMetrics like API are strongly needed, not just for Rich Text editor and
not just for UI controls and should be the priority. Other things that can
be built outside the openjfx, like a rich text editor, are nice to have but
not a priority.

I agree that things like rich text editors can be built outside first and
then integrated. I believe this is the best workflow has it allows for
prototyping,  experimenting,  getting feedback from users and iterating.
And when it has a pretty solid API and user experience it can be integrated
inside the openjfx library, because then things will get much more
complicated to change and break.

Cheers,
