* circuit - Random electronic components floating around

- * version 1.3
+ * version 1.4
*
* Since version 1.1: added to-220 transistor, added fuse
* 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
