Transparent PNG
Smooth graphics

* Added T-DISPLAY-S3 i8080 support for more than 33 data pins (#2296)

* Modified the ESP32-S3 I8080 interface's support for data pins above 33 pins.

* Added T-DISPLAY-S3 support

* Update Setup206_LilyGo_T_Display_S3.h

* Eliminate need for TFT_DATA_PIN_OFFSET_EN in setup file

* Update TFT_eSPI_ESP32_S3.h

* Update User_Setup_Select.h

* Add new init sequence for LilyGo T Display S3

* Add smooth arc drawing function

Update ESP8266 architecture reference
Add pushMaskedImage() to render 16bpp images with a 1bpp mask (used for transparent PNG images plus with sprites)

New functions added using drawArc:
drawSmoothArc
drawSmoothCircle
drawSmoothRoundRect
New sqrt_fraction() added to improve smooth graphics performance on processors without a FPU (e.g. RP2040)

Faster alphaBlend() function added which retains 6bpp for green

Rename swap_coord() to transpose()

* Update TFT_eSPI.cpp

* Add arc examples

The use of a setup file in sketches only works in certain circumstances.

Enable HSPI configuration for ESP-IDF

Update Using ESP-IDF.txt

clarified instructions for not using KConfig file

Note: The library author (Bodmer) does not use the ESP-IDF and therefore does not provide support for that route!

// For RP2040 processor and 8 or 16 bit parallel displays:
// The parallel interface write cycle period is derived from a division of the CPU clock
// speed so scales with the processor clock. This means that the divider ratio may need
// to be increased when overclocking. I may also need to be adjusted dependant on the
// display controller type (ILI94341, HX8357C etc). If RP2040_PIO_CLK_DIV is not defined
// the library will set default values which may not suit your display.
// The display controller data sheet will specify the minimum write cycle period. The
// controllers often work reliably for shorter periods, however if the period is too short
// the display may not initialise or graphics will become corrupted.
// PIO write cycle frequency = (CPU clock/(4 * RP2040_PIO_CLK_DIV))
//#define RP2040_PIO_CLK_DIV 1 // 32ns write cycle at 125MHz CPU clock
#define RP2040_PIO_CLK_DIV 2 // 64ns write cycle at 125MHz CPU clock
//#define RP2040_PIO_CLK_DIV 3 // 96ns write cycle at 125MHz CPU clock

Fix H and V gradient use in sprite
New ESP8266 board package uses RDUINO_ARCH_ESP8266
old package defined ESP8266

Fix typo and remove unnecessary error in TFT_config.h

1. RGB configuration was configured incorrectly, and caused re-definition warnings.
2. MISO pin is not always set, so shouldn't trigger a compilation error (see e.g. `Setup25_TTGO_T_DISPLAY.h`).

Create Setup301_BW16_ST7735.h for BW16-based Boards
