Using the New ESP32 LCD Panel API With htcw_gfx and htcw_uix

The ESP LCD Panel API introduces a new way to interface with LCDs using i8080, RGB, SPI or I2C interconnects and DMA on supported platforms. Using it requires a different way of coding to the display than stateless libraries like TFT_eSPI and htcw_gfx normally allow for. Here's how to use this technology with htcw_gfx, and htcw_uix.
