1edfe6c680 Fic #311
Pixel function used wrong width and height for bounds check.
Remove String variable in smooth font code (not used)

26d7e4038a Fix touch screen handler
The touch screen handler was broken for the ESP8266 only. The library
uses SPI write only configuration for ESP8266 so the SPI buffer can be
recycled and it was left in write only mode. The library now switches
back to read & write mode at the end of a transaction.

1e1e888fa0 Support extended font formats
Adafruit_GFX font support extended to Unidode Basic Multilingual Plane
Print stream deocdes UTF-8
Smooth font ascent and descent (affects line spacing) changed to rely on
metrics provided by Processing IDE (issue #303)
Bug fix for font rendering with no background on RLE native fonts

61dfb2b4ac Extended character set suport for Adafruit_GFX format fonts
Supports Adafruit_GFX compatible font format with characters in the range 32-255.

Note that the font rendering functions expect UTF-8 encoded characters/strings.

caef4519f3 Improve bounds checking update CS management
Add bounds checking to graphics functions
Rationalise variable types and style used to minimse type casting needs
(this change ended up being a more extensive refactoring than
anticipated - but once started...)
Add version reporting to diagnostic sketch
Boost PDQ graphicstest performance

054a824eb8 Add ESP32 VSPI or HSPI port option + others
If the VSPI port is in use and pins are not accessible (e.g. TTGO
T-Beam)
then add or uncomment the following line in the setup header file:
//#define USE_HSPI_PORT

Minor performance tweaks for ESP32 to minimise the occurence of the slow
transaction overhead.

setAddrWindow now takes xstart, ystart, width and height as inputs

Multi-sample raw touch x and y for noisy displays

Example update for setAddrWindow change compatibility

96228cbf44 Add Sprite rotation and examples
Sprites can be rendered rotated with defined pivot points, 3 new
examples have been added "Rotated_Sprite_1/2/3".
The FLASH bitmap example has been moved to the Generic examples folder.
Boundary checks have been added to pushImage()
A new scrolling and wrapping in a Sprite example has been added.

e8c201db5e Update touch handler
Added new function that sketch can call to convert raw ADC x and y
values to calibrated screen coordinates:
tft.convertRawXY(&x, &y);

Redunced required number of SPI transfers needed to read raw values.
Changed mode so PENIRQ pin is enabled so users sketch can read this
signal (if needed).

See issue #279.

41dea61bfd Correct #263, add setup file for 160x80 TFT, add invert option
Fixed bug where wrong wodth was returned for 1bpp Sprite
Improved speed for copying a 1bpp Sprite into another 1bpp Sprite (
affects Sprite pushImage() function only)
Added option to setup for colour inversion

1cf2305e4d Add capability to read TFT SDA bi-directional pin
Tested on an ESP32 with ST7789V display
SDA read is very slow on an ESP8266 (to be investigated)
Added new setup #define TFT_SDA_READ
Add new ESP32 and ESP8266 compatible in example/Generic folder to test
capture of TFT screen

7a3d6bcab9 Minor performance improvements for ESP32
Remove legacy changes for double buffered SPI
Eliminate unecessary ESP32 SPI read/modify write
Eliminate two stage control bit changes (may impact some diplays with
setup/hold  timing and show ESP32 hardware register bug?)
Add single register write for CS and DC command
Make setAddrWindow smarter (as used in previous AVR library)
Improve compatibility with GFX sketches
Re-arrange comments slightly to improve positioning

9666314eb6 Support for ESP32 PSRAM added
If PSRAM is fitted and enabled the Sprites are now created in PSRAM.
This makes multiple full screen buffers possible!

1a0b37097a Add new anti-aliased (smooth) font examples + bug fixes
Four new examples have been added to show different methods of rendering
the anta-aliased fonts.  A few minor bugs have been corrected associated
with the font rendering. drawNumber and drawFloat handle fixed width
mono fonts with no digit movement.

Update Sprite.cpp
Hi,
I found a bug.

_width and _height need to be initialized properly.

That is because they are used in drawString(). Lines 4118 and 4120 in TFT_eSPI.cpp.
