Adafruit & Xark's benchmark for LCD screens showcased with the TFT_eSPI library and a "generic" LCD library. Since TFT_eSPI is optimized for ESP32 microcontroller that we use in WiPhone, it achieves speedup by a factor of 12 in some tasks.

Hardware:
- ESP32 microcontroller
- 320x240 TFT screen with ST7789 driver
- 4-wire SPI interface

Chronology:
00:00 - Bodmer's TFT_eSPI library benchmark
00:15 - benchmark of a slower graphics library
00:54 - slow motion of TFT_eSPI benchmark (240fps)
