Lib for the new LCD Display with ILI9341 controller Modified for huge fonts (>255 bytes/char). Needs modified font.h files with 2-byte size parameter. Window size is set on a per-character basis to minimise the number of pixels written (speed-up, plus better detection of whether one last character will fit on the current line). NUCLEO & NXP DMA-enabled versions are modified but untested.
