pdf-font: accept classic CIDFontType0 font files#164
Merged
Conversation
Preserve the embedded Type 1 program format on Type0 descendant fonts, so CIDFontType0 descriptors with classic /FontFile streams parse and render instead of failing as unsupported. Thread the stored program format into the canvas Type1 renderer so classic Type 1 CID fonts use the existing rendering path. Add a regression test for a CIDFontType0 font descriptor with an embedded classic Type 1 /FontFile stream. Co-authored-by: Codex <codex@openai.com>
