Detailed Description

The menu icons, drawn from primitives rather than stored as bitmaps.

Each icon is a few rings, capsules and strokes scaled to the requested size. A drawn icon is sharp at any size and needs no image data in flash. Every icon is drawn centred on the point it is given, inside a box of size x size px around it.
