// -------------------------------------------------------------------------
Alsp added and example for GFXcanvas that demonstrates the impact of rotation
on pixel layout and also demonstrates getting a pixel based on raw
physical coordinates.
Adafruit_GFX overrides one of the Print::write() functions.
The rules of overload resolution say that all the overloaded options
need to be visible in the class where the first option is found.
Since Adafruit_GFX only overrides write(uint8_t), the other version,
write(const uint8_t *buffer, size_t size) cannot be called on a
Adafruit_GFX display from sketches.
This change adds the "using" directive, which tells C++ to consider
all of Print's write members to be in scope of Adafruit_GFX, even
though only one is overridden.
* Fix compiler warning [-Wunused-const-variable=]
Compiling a sketches that uses this library can report a warning
about the const variable `font` being defined, but never used.
Work around this by defining a (static inline) function which
references the variable.
* Remove unused variable (compiler warning)
