Solution to Issue #85

I need this in my project but will add a switch.

Permits backwards compatibility

As requested in Issue #79

Function names are compatible with Adafruit_GFX

Also trimmed out duplicate keywords

Correct capitalization of keywords.txt

Incorrect capitalization of the filename caused keywords highlighting to not work on filename case sensitive operating systems.

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

If touch not used dummy getTouch missing the new threshold parameter.

getTouch accepts a third optional pressure threshold, default is 600,
increasing means harder presses are needed.
getTouch(uint16_t *x, uint16_t *y, uint16_t threshold = 600);

Allow externally defined configuration rather than User_Setup.h modifications in library

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.

width or height over 127 pixels got converted to a negative number!

Added example "Sprite_scroll"
Tidy up virtual function list
Add PROGMEM bitmap image functions

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.

The 32 bit alignment offset must be checked for every line to prevent crash with odd pixel count lines.

Do not adjust x datum for characters that have a positive offset.

Prevent memory access to non-existant Sprite memory areas which would
cause a processor reset.
