Pasting a definition like:
<!-- Generator: Adobe Illustrator 17.1.0, SVG Export Plug-In -->
<svg version="1.1"

x="0px" y="0px" width="247.7px" height="83.7px" viewBox="0 0 247.7 83.7" enable-background="new 0 0 247.7 83.7"
xml:space="preserve">

</defs>
<rect id="square_1_" x="0.5" y="0.5" fill="#FFFFFF" stroke="#000000" stroke-miterlimit="10" width="137.3" height="82.7"/>
<circle id="circle_1_" fill="#FFFFFF" stroke="#000000" stroke-miterlimit="10" cx="205.8" cy="41.8" r="41.3"/>
</svg>
Would allow to directly describe problems visually easily, while right now that can be done through image insertion:
Why can't the editor allow inline SVG, since it doesn't impose any security threats that I'm aware of.
