Font generator descriptions added to readme

[the-this-pointer]

Hi
I've created a font generator for the library to save my time on another library! It still have some work to get the whole font file generated, at this time it can help creating/editing a single character or importing a character from the font file. I'll complete the project on my spare time.

Contribution appreciated! Thanks.

Resolves #3 , #20 , #24 , #35 , #53 , stm32-ili9341#3 , stm32-ili9341#1

Thanks for the font generator!

Unfortunately it doesn't quite address the linked issues because:

At this time, just Microsoft Windows is supported

Personally I'm using MacOS. Many people I know use Ubuntu.

I linked the generator in #3 but I'm afraid it can't be recommended in README as long as it's not cross-platform, sorry.

Hi, yeah, you right. I will develop it in my spare time to support multi-platform.
The application will be multi-platform IF I change the open file dialog and clipboard source code.
Thanks for your recommendation.
