Use Optional to determine if appearance stream as fontchromium/3388
This CL changes the CPDF_DefaultAppearance code to remove the HasFont method and change GetFont to return an Optional. This forces all the call sites to verify a font was returned correctly and removes the need for the duplicate appearance stream parsing. Bug: chromium:827430 Change-Id: If09e0a7d3f7dd63ad77b97a5a388127e4a02da61 Reviewed-on: https://pdfium-review.googlesource.com/29610 Commit-Queue: Ryan Harrison <rharrison@chromium.org> Reviewed-by: Ryan Harrison <rharrison@chromium.org>
