[BUG] Rendering issue: Type3 fonts are not currently supported

[gunnsth]

Description

When rendering the attached PDF there is an error. Problem seems to be lack of support for rendering Type 3 fonts. Type 3 fonts have glyphs stored as PDF objects (content stream), so it should be fairly easy to support going forward.

Expected Behavior

Expected to run without issues and create an image rendering of the PDF page.

Actual Behavior

Steps to reproduce the behavior: 1, Run the rendering example

$ ./pdf_image_render out image_cliprect.pdf
2020/01/22 18:56:25 Image rendering error: Type3 fonts are not currently supported
