* Since version 1.2: random display digits, LED improvements (flickering)
* Since version 1.3: ICs look better, font textures, improved normals to
* eliminate segmenting on curved surfaces, speedups
+ * Since version 1.4: Added RCA connector, 3.5mm connector, slide switch,
+ * surface mount, to-92 markings. Fixed ~5min crash.
+ * Better LED illumination. Other minor changes.
