Thanks for the examples.
I've tried this and it really works!
It feels somewhat slower (I'm using user-defined characters) but that
probably doesn't warrant its own driver.

So I'll contribute a documentation change that adds an example of how
to use the I2C-enabled version of the display, this may be non-obvious
to others. I'll start a new thread for this, stay tuned...

@Miguel: Thanks for your detailed feedback on coding style, I'll use
this next time ;-)
