Incorrect rendering of Type3 character

Hi Team.

We got a report from one of our customers that their images weren't rendered correctly. Looking into it, we found that a Type3 character contained an image. 

That image was present on the character glyph resource table and not the font resource table which is a bit strange if you read the specification this should not be allowed. 

Then again Chrome, Opera, IE 11, and Adobe render this file correctly. But Safari, Firefox, and Poppler are not rendering this PDF correctly.

I've created a small patch that will solve this issue.

Best regards

Daniel
