DMA for RP2040, ESP32 - see "'Boing' ball demo" example taken from TFT_eSPI repository.
Due to redefinition of hardware/pio.h in tsdesktop update env/rp2040_pio.h & env/rp2350_pio.h.
In Setup, comment out OVERLAID constant not to go the way in running DMA.
Fill gradient modernization finished - see idyll example.
Rename drawPixel1->drawClippedPixel & drawPixels->drawClippedPixelRec for more understanding gfx.
