3D Font for Holographic and 3d displays...

A font is only 2D up until the primary Z-Axis is specified this provides the depth of the 3d scale, the middle Z axis is at 50% the length, if you specify a -Z primary axis it is the same as absolute z except it hugs the rear of the plainer display.

There is a secondary Z-Axis with pitch of a spline, this when it is negative flip the variables to type 2 of 3d and is still treated as as the absolute Z-Axis of pitch otherwise the depth of the spline node.
