Inline shape
============
Word allows a graphical object to be placed into a document as an inline
object. An inline shape appears as a ``<w:drawing>`` element as a child of
a ``<w:r>`` element.
Candidate protocol -- inline shape access
-----------------------------------------
The following interactive session illustrates the protocol for accessing an
inline shape::
>>> inline_shapes = document.body.inline_shapes
>>> inline_shape = inline_shapes[0]
>>> assert inline_shape.type == MSO_SHAPE_TYPE.PICTURE

MS API
------
The Shapes and InlineShapes properties on Document hold references to things
like pictures in the MS API.
* Height and Width
* Borders
* Shadow
* Hyperlink
* PictureFormat (providing brightness, color, crop, transparency, contrast)
* ScaleHeight and ScaleWidth
* HasChart
* HasSmartArt
* Type (Chart, LockedCanvas, Picture, SmartArt, etc.)

* 17.3.3.9 drawing (DrawingML Object)
* 20.4.2.8 inline (Inline DrawingML Object)
* 20.4.2.7 extent (Drawing Object Size)
Minimal XML
-----------
.. highlight:: xml
This XML represents my best guess of the minimal inline shape container that
Word will load::
<w:r>
<w:drawing>
<wp:inline>
<wp:extent cx="914400" cy="914400"/>
<wp:docPr id="1" name="Picture 1"/>
<a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main">
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/picture">
<!-- might not have to put anything here for a start -->
</a:graphicData>
</a:graphic>
</wp:inline>
</w:drawing>
</w:r>
Specimen XML
------------
.. highlight:: xml
A ``CT_Drawing`` (``<w:drawing>``) element can appear in a run, as a peer of,
for example, a ``<w:t>`` element. This element contains a DrawingML object.
WordprocessingML drawings are discussed in section 20.4 of the ISO/IEC spec.
This XML represents an inline shape inserted inline on a paragraph by itself.
The particulars of the graphical object itself are redacted::
<w:p>
<w:r>
<w:rPr/>
<w:noProof/>
</w:rPr>
<w:drawing>
<wp:inline distT="0" distB="0" distL="0" distR="0" wp14:anchorId="1BDE1558" wp14:editId="31E593BB">
<wp:extent cx="859536" cy="343814"/>
<wp:effectExtent l="0" t="0" r="4445" b="12065"/>
<wp:docPr id="1" name="Picture 1"/>
<wp:cNvGraphicFramePr>
<a:graphicFrameLocks xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" noChangeAspect="1"/>
</wp:cNvGraphicFramePr>
<a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main">
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/picture">
<!-- graphical object, such as pic:pic, goes here -->
</a:graphicData>
</a:graphic>
</wp:inline>
