Hey @Jatin24062005, rather than making a special case for fonts here, are we able to update the doc comments for loadFont to more accurately reflect the different possible overloads?

Hey @davepagurek ! I saw that @limzykenneth mentioned some contributors are already working on the documentation. Should I still proceed with updating the doc comments for loadFont(), or would it be better to coordinate with them to avoid duplicate efforts?

If you're still up for working on it, we can just make sure @GregStanton and @perminder-17 know you're working on this one!

@davepagurek I believe @GregStanton and @perminder-17 might be a better fit for handling the documentation updates, as they have more experience in this area. I haven’t worked much with graphics, which makes me a bit less confident in making the necessary changes.
However, if you can guide me on the key updates needed, I’d be happy to give it a try!
