SVG to PNG fails

[Mike Thomas]

Hi there.

The attached SVG converts to a blank PNG using the code below under stackage nightly-2016-09-01. Both files are in the attachment.

The SVG displays correctly under Chrome and the Atom editor SVG viewer. Atom also correctly converts the file to a PNG.

Please let me know what you think. If it's a Rasterific problem I'll pass it on to them.

Thanks

Mike Thomas.

You have a space in front of your M path command, which is not handled correctly in svg-tree.
