* 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 TFT configuration (user setup) can now be included inside an Arduino IDE sketch providing the instructions in the example Generic->Sketch_with_tft_setup are followed. See ReadMe tab in that sketch for the instructions.
A new background rendering approach is used for smooth fonts which almost eliminates flicker. tft.print... can now be used with a background rendered for smooth fonts. Font_Demo_1/2/3... examples have been updated.
A new "docs" folder has been created and files moved there. The Tools folder now only contains support tools.
#1757 fixed by using Arduino calls.
A new USER_SETUP_ID parameter can be added to setup files and checked via a new verifySetupID(id); function.
Version raised to v2.4.50
Sprite class uses TFT_eSPI setBitmapColor - fn deleted
Small performance improvement to RP2040 SPI PIO
Typo corrections
Correct (unused) tft_Write_32 for STM32
Update HX8357D rotation code
Enable software reset for ILI9486
Add preliminary RM68120 support
The RP2040 processors can now drive 8 bit parallel and SPI displays using the PIO hardware.
The PIO offloads the processor by providing:
1. PIO managed setWindow sequence
2. PIO managed block and screen fill
