Detailed Description

A named user coordinate system (UCS).

A UCS defines a local frame in world space through an origin point and three orthonormal axes. The axes must form a right-handed system.

A UCS named "world" (the identity frame) is created automatically on initwindow() / initgraph() and cannot be destroyed. Classic BGI drawing is unaffected by the UCS system.
