A New Approach for a General TFT Library.

• The purpose of this Library and its design is to make additions easy.
• The initial commit served as "proof of concept", with HVGA TFT on MEGA, DUE, and 3.5" RPI HVGA on SPI
• This library supports a collection of TFT displays I bought to learn from and to learn from other libraries
• It supports some "exotic" displays for Arduino that were not made to use with Arduino IDE or Arduino boards
• I recommend to use other common Arduino TFT libraries whenever possible, as these are better supported
• my recommendations are MCUFRIEND_kbv, TFT_eSPI, and the whole range of Adafruit libraries

• added 16 bit command transfers to all GxIO classes for parallel 16 bit interfaces to support OTM8009A
• added GxIO_DUE_P16_R_SHIELD class (variant of GxIO_DUE_P16_DUESHIELD, e.g. for rDuinoScope)

• new src directory structure avoids the need for .cpp includes
• only header files includes are needed
• Arduino IDE 1.8.x automatically includes needed code from .cpp files
• DO NOT include .cpp files with this version, linker would complain
• src directory structure makes GxTFT a more usual Arduino Library

• Added OTM8009A support for 3.95" & 4.7" TFTs with FSMC connector on STM32 boards

• Added FSMC GxIO classes for STM32 GxIO_STM32F1_FSMC and GxIO_STM32F4_FSMC and FSMC examples
• Added FSMC and P16 GxIO classes for STM32F407ZGM4 board

• Renamed GxIO classes for HVGA on MEGA and DUE
• Added read support to GxIO classes (partially tested only, some shields are output only).
• Updated GxCTRL and its subclasses; added GxCTRL_RA8875S
• Updated read support; read support is controller specific, issues remain to be investigated.
• Added GxTFT & RA8875P

• Added GxIO classes for TIKY 5inch display
• Fixed TIKY GxIO classes and GxCTRL_ILI9806

• HVGA on MEGA
• HVGA on DUE
• HVGA on SPI (3.5inch RPI Display)
