1. Ability to swap bytes in pushColors() and pushImage()
2. pushImage() will handle FLASH stroed images
3. pushImage() will accept a transparent color
4. pushRect() deprecated but still works
5. setSwapBytes() to set swapping bytes in color for pushImage() and
pushColors() true or false
6. getSwapBytes() returns swap bytes parameter
7. fillCircle() and fillCircleHelper() changed to use horizontal lines
to speed up plotting in a sprite
8. fillTriangle bug fix by moving spi_begin()
9 Small performance improvement to setAddrWindow()
10. pushColor() bug fix for swapped bytes
11. pushColors() performance improvement for ESP8266 and add optional
byte swap parameter, accepts higher pixel count
12. move spi_begin() later in drawLine() incase fn returns early
13. add spi_end() in drawLine incdae return occurs early
14. Add color332() fn to convert 16 bit to 8 bit colour
15. Sprite: createSprite() checks if sprite already created and returns
pointer if it does
16. Sprite: one extra "off-screen pixel added to a sprite to point
out-of-bounds setWindow coords to
this avoids extra bounds checks in push/write color
17. Sprite: setColorDepth allows changing of depthe for existing sprtie
and returns a new pointer to the new sprite
18. Sprite: pushImage() accepts a swapped byte parameter
19. Sprite: setSwapBytes() to set swapping bytes in color for
pushImage() and pushColors() true or false
20. Sprite: getSwapBytes() returns swap bytes parameter
21. Sprite: setWindow deals with duff out of sprite coords.
22. Sprite: bug in draw char corrected which could draw too many
over-writing pixels
Adding ability to load settings from the calling program rather than modifying the library for each project that uses it. This is mostly for PlatformIO IDE which manages the libraries differently than Adruino IDE.
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.
