Can now specify a colour that will not be plotted so some part of the
Sprite are "transparent" and the TFT backforund shows through. New
example added for demonstration.
This commit fixes an issue when setting screen width
and height from the constructor (e.g., user sketch),
followed by setRotation(i). Previously, setRotation
used TFT_WIDTH and TFT_HEIGHT, ignoring user overrides.
Sprites (images) can now be created in RAM, written to with text and
graphics and rendered to screen quickly, this makes it easier to get
flicker frre screen updates.
ESP8266 can typically create up to a 160x128 sprite, and ESP32 about
200x200 pixels. 16 bit colour only at the moment, may soon implement 8
bit colour to reduce RAM.
Touch reliability improved by using pressure and double sampling. Added
Adafruit compatible Button class. Added touchscreen on/off and keypad
examples.
There is a silicon bug in the ESP32, writing the same value to a
register twice sometimes fails. TFT_CS needs a delay though, so the fix
is to write two different values to the register.
Reference to particular drivers in examples have been removed as
multiple display drivers are now supported.
Tabs replaced by spaces in header file by file editor.
RPi TFT with write strobe SPI clock rate dropped to 20MHz (display
cannot cope with new high rate siWriteBlock() function)
