* Fixed and Added more fonttable support for PCF2119R_3V3, Added HD66712 controller.
* 2015, v21: WH, Added LCD32x2 defines and code, Fixed KS0073 DL=1 init for SPI, Added defines to reduce memory footprint (LCD_TWO_CTRL, LCD_CONTRAST, LCD_UTF8_FONT)
* Added SPLC792A controller, Added UTF8_2_LCD decode for Cyrilic font (By Andriy Ribalko). Added setFont()
+ * 2019, v22?: AR Changed wait_ms to ThisThread::sleep_for and added (char) casts for int conversion on parameters passed to a couple of function definitions. MBED 5.xx
