How to use the 'render.setPrintFunc()' function

[RodrigoRDA]

First of all, I would like to congratulate you on creating this library, which greatly facilitates the management and use of fonts in ESP32 projects.

However, the examples you made available in the 'examples' folder cover very little of the functions present in the 'keywords.txt' file. Could you create a new generic example that explains and demonstrates how all the functions in this library work?

For example, the 'render.setPrintFunc()' function: what is it for and how do I use it? Would it be possible to use it to make my 'tft.print()' function be used instead of 'render.printf()'? Or is this not the purpose of this function in your library?

Your library is very good, but the documentation (explanation of the functions) leaves a lot to be desired.

Thank you for using this library and I apologize for the lack of sample code.
Some documentation is available on GitHub Pages.

The setPrintFunc method is used to wrap the standard output of the library.
For example, if your microcontroller has multiple Serial outputs, you can output information such as library errors to any Serial.

render.setPrintFunc(Serial1.print); 

Since it is common to use Serial objects in Arduino, you should use the setSerial method, which is easier to handle.

render.serSerial(Serial1);

I think one important contribution would be to list what sample code is needed.

Thank you.
