Internet Explorer IndexSizeError on Drawer.blendSketch context.drawImage

See original GitHub issue

Demo: http://plnkr.co/edit/ormkIn

It works fine on Chrome, but IE throws an error and the image freezes (cannot pan or zoom). There are multiple Google results for “ie drawImage IndexSizeError” but I could not get it to work.

IE spec says:

IndexSizeError The numeric arguments are not valid (for example, the destination is a 0x0 rectangle). Versions earlier than Internet Explorer 10 use INDEX_SIZE_ERR.

EDIT: homeFillsViewer: true makes IE throw the error consistently. homeFillsViewer: false still throws the error, but if you pan or zoom when the image first shows up, sometimes it does not throw the error and everything works afterwards.
