Proposal: Add glue points to 3D objects

Add glue point to 3D objects



Glue points are designated points on
the area of a drawing object to which a connector shape can connect. A
<draw:glue-point> element creates a single user-defined glue point
if placed inside a drawing object element. Currently <draw:glue-point>
supports almost all drawing shapes except 3D objects. The following proposal
adds <draw:glue-point> to <dr3d:scene>.



9.4.1 Scene

<define name="dr3d-scene">

        <element
name="dr3d:scene">

the <dr3d:scene> element are:
