For 1.6 I would like to eliminate all unnecessary image fallbacks.
At present the only remaining work to be done is to add native support
for gradients with EXTEND_REPEAT and EXTEND_REFLECT.

For 1.8 than plan is:
  - Improved text extraction
  - Metadata API
  - Reduce the PDF file size. This includes:
     - Don't re-embed images, gradients and meta surface patterns
       each time they are used
     - Merge glyphs into the same string where possible (#11612)
     - JPEG support
