Maxint R&D / Mbed 2 deprecated RETRO_LCD_PerformanceTest

Simple program for the RETRO to compare the performance of the DisplayN18 and LCD_ST7735 libraries.

Dependencies:   LCD_ST7735 mbed

This is a very simple program for the RETRO to compare the performance of some of the primitives of the DisplayN18 and LCD_ST7735 libraries

WARNING - WARNING - WARNING

If you're sensitive to ugly coding techniques, lack of best practice, ignorance of proper design patterns, abuse of object orientation or to total disregards of any coding guidelines, then don't - I repeat - DON'T look at this code...

P.S. Regardless the performance, I do think the N18 library has a much nicer font!
