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.

Images/sprites overlapping both sides of the display were not correctly
cropped.
Option added to allow RGB<>BGR colourr swap option to be used.
ESP8266 Wemos D1 R1 pin numbering difference accomodated.
TTGO T4 setup changed to use HSPI port.

Setup 135 is for TTGO T Display (ESP32)
Plus minor tweaks to avoid some warnings

Correct compile error.

Added support for ST7789 135 x 240 display which needs offsets
Added Setup135_ST7789.h as an example setup file for ESP8266

Corrected font 2 rendering issue #402
Corrected NULL pointer issue #400
Changed grave ` character (key for this character is left of numeral 1
key) to degree symbol in font 2
Change setup24 so DC pin is not D3
