RPi MHS-4.0 inch Display-B type display now supported.

The s60sc Adafruit_Touch library fork for the ESP32 parallel mode uses the TFT_WR pin as an analogue input to read the screen resistance.  The TFT_eSPI library kept TFT_CS low permanently for performance reasons, but when used with the touch library a low analogue value on the TFT_WR pin will write spurious data to the display. 

This change toggle TFT_CS so it is only low during TFT parallel bus writes. The performance reduction is small.

ILI9488 not compliant to datasheet with extra clock pulse?

Add TTGO T-Wristband config

Update to accommodate smooth font rendering, which need a background colour specified.

Add: Destructor of TFT_eSprite.

By default the grave accent will be drawn as a degree symbol, a #define
has been added so it can be swapped back to the grave accent.

Fix TextFont 2 (Font16.c) backslash(0x5c) looks like slash.

Callback allows anitaliased fonts to be rendered over colour gradients
or images.
"Smooth_font_reading_TFT" example added
"Smooth_font_gradient" example added
Minor changes to avoid signed/unsigned comparison warnings.
