Proposal: Add glue points to 3D objects

[Zhi Yu Yue <yuezhiyu@cn.ibm.com>]

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">
         
      <ref name="dr3d-scene-attlist"/>
         
      <ref name="common-draw-position-attlist"/>
         
      <ref name="common-draw-size-attlist"/>
         
      <ref name="common-draw-style-name-attlist"/>
         
      <ref name="common-draw-z-index-attlist"/>

      <ref name="common-draw-caption-id-attlist"/>

      <optional>
         
              <ref

      </optional>
         
      <zeroOrMore>
         
              <ref
name="dr3d-light"/>
         
      </zeroOrMore>
         
      <zeroOrMore>
         
              <ref

      </zeroOrMore>
         
      <zeroOrMore>
       
               
               
        <ref name="draw-glue-point"/>
       
               
               
</zeroOrMore>
        </element>
</define>

The elements that may be contained in the <dr3d:scene> element are:

• ...
• Glue points ¨C see section 9.2.19.
