Fork of SPI_TFT by Peter Drescher

See Components - RA8875 Based Display

Enhanced touch-screen support - where it previous supported both the Resistive Touch and Capacitive Touch based on the FT5206 Touch Controller, now it also has support for the GSL1680 Touch Controller.

-/// @todo Add APIs for the 2nd RA8875 PWM channel. If the frequency can be independently
-///     controlled, it could be used as a simple beeper.
+/// @todo Move the global enums into the class (e.g. NOFILL becomes RA8875::NOFILL) to
+///     avoid namespace clashes.
+/// @todo Integrate the touch as a runtime linkable feature, which can then eliminate
+///     the huge memory footprint for the GSL1680 firmware when it is not needed.
+/// @todo Integrate installed font-rom.
 /// @todo Figure out how to "init()" in the constructor. I ran into some issues if
 ///     the display was instantiated before main(), and the code would not run,
 ///     thus the exposure and activation of the init() function. If the constructor
 ///     was within main(), then it seemed to work as expected.
+/// @todo Add Scroll support for text.
+/// @todo Add Hardware reset signal - but testing to date indicates it is not needed.
+/// @todo Add high level objects - x-y graph, meter, others... but these will
+///     probably be best served in another class, since they may not
+///     be needed for many uses.
