Custom polygon generation #597
Description
To generate a custom polygon shape, it looks like a minimal XML chunk would look a bit like this:
<p:sp>
<p:nvSpPr>
<p:cNvPr id="SOMEIDNUMBER" name="OBJECTNAME"/>
<p:cNvSpPr/>
<p:nvPr/>
</p:nvSpPr>
<p:spPr>
<a:xfrm>
<!-- x and y position of shape -->
<a:off x="2917861" y="585627"/>
<!-- width and height of shape -->
<a:ext cx="2732926" cy="1705510"/>
</a:xfrm>
<a:custGeom>
<a:avLst/>
<a:gdLst/>
<a:ahLst/>
<a:cxnLst/>
<a:pathLst>
<a:path>
<a:moveTo>
<a:pt x="904126" y="0"/>
</a:moveTo>
<a:lnTo>
<a:pt x="2732926" y="657546"/>
</a:lnTo>
<a:lnTo>
<a:pt x="1952090" y="1705510"/>
</a:lnTo>
<a:lnTo>
<a:pt x="297950" y="1664413"/>
</a:lnTo>
<a:lnTo>
<a:pt x="0" y="708917"/>
</a:lnTo>
<a:lnTo>
<a:pt x="904126" y="0"/>
</a:lnTo>
<a:close/>
</a:path>
</a:pathLst>
</a:custGeom>
<a:solidFill>
<a:srgbClr val="FF0000"/>
</a:solidFill>
</p:spPr>
</p:sp>
There's also arcTo,cubicBezTo and quadBezTo. It seems like it would be possible to convert an SVG path definition to this path definition (if a width/height was passed along too). This is just enough to get a shape displayed but is missing definitions for shape handles etc.
a:off and a:ext can be minimised (cx and cy for a:ext set to 1, and x/y set to 0 for a:off) but that means that the point positions need to be absolute, and the bounding box on selection of the object is off (which is an ok artefact to have I think).
