The OverlapXYOfft command sets the XY offset of the shade primitive relative to the body primitive at
shading drawing. Shadow shape is same as body.

Explanation
ShadowXY
0000_0000 ShadowXY command sets the XY offset of the shade
primitive relative to the body primitive.
ShadowXYcompsition
0000_0001
ShadowXYcomposition command sets the XY offset of
the shade synthetic primitive relative to the body
primitive.
It command synthesizes a shade from the relationship
between the XY offset set using ShadowXY and this
XY offset. This command is enabled for only lines.

S_Z Offset

O_Z Offset
The OverlapZOfft command sets the Z offset of the shade primitive relative to the body primitive, sets
the Z-offset of the edge primitive relative to the body primitive, and sets the Z offset of the interpolation
primitive relative to the body primitive, with the top-left rule non-applicable in effect.
At this time, the following relationship must be satisfied when, for example, GREATER is specified for
the Z value comparison mode:
Body primitive > Top-left rule non-applicable interpolation primitive
> Edge primitive > Shade primitive

Explanation
0000_0000
Origin command sets the Z offset of the body primitive.
When drawing one primitive below the other primitive (for
example, when drawing a solid intersection), this Z offset is
changed. When drawing an ordinary intersection, set the
same Z offset as other primitives.
0000_0001 NonTopLeft command sets the Z offset of the interpolation
primitive, with the top-left non-applicable.
0000_0010 Border command sets the Z offset of the edge primitive.
0000_0011 Shadow command sets the Z offset of the shade primitive.
0000_0111 Packed_ONBS command sets the above four types of Z
offsets.
