SSD1283A for Arduino

This library supports SSD1283A to use with Adafruit_GFX and/or LCDWIKI_GUI.

The code is extracted from LCDWIKI_SPI and adapted for single controller use and Adafruit_GFX.

Only HW SPI is supported.

Version 1.0.3

• fixed rotation (rendering canvas ok for all 4 rotations)

Version 1.0.2

• added template class GFXcanvas16T, uses dynamic memory space instead of heap space
• added method drawRGBBitmap() for PROGMEM bitmaps

Version 1.0.1

• added method drawRGBBitmap(), e.g. for fast canvas rendering
• use rotation for drawing to the canvas, but use only rotation 0 or 3 for rendering the canvas to screen.
• the "quick test" example src/src.ino shows the issue

Version 1.0.0

• improved rotation somewhat, see general remarks
• fixed clipping (drawPixel, fillRect)
• optimizations and cleanup

Version 0.0.6

• fixed rotation

Version 0.0.5

• fast pushColors() optimized also for Teensy 3.2
• cleaner implementation of fast pushColors()

Version 0.0.4

• fix some copy/past or replace errors

Version 0.0.3

• added example graphicstest_through_canvas.ino
• added faster pushColors() method, optimized for ESP32, ESP8266

Version 0.0.2

• fixed SPI transaction nesting issue, causing hang on ESP32 and other platforms
• still a preliminary version

Version 0.0.1

• initial preliminary version for initial check-in
• works with my "Transflective Display Module LCD Display DIY SPI Serial Port 130*130 Communicate for Arduino"
• https://www.aliexpress.com/item/4000116854157.html
• rotation does not work correctly
