(macro) void gdx_DecNumOfApproxPnts()

# Purpose

Decrements the number of GDX linear approximation points in the currrent GDX linear approximation workspace

# Description

Decrements the count of linear approximation points created in the current GDX linear approximation workspace. No error checking is performed and it is assumed that a workspace is currently allocated and at least one of the linear approximation points has been set (See gdx_SetApprox3DPnt or gdx_AddApprox3DPnt).
