Overview

Inline image operators (s8.9.7). Inline images embed raw image data directly in the content stream, framed by BI ... ID ... EI. They're an alternative to /XObject /Image for one-shot images: smaller overhead per image, no /Resources entry needed, but the bytes live in the content stream so they can't be reused.

The Parser detects BI ... ID ... EI and yields a single BeginInlineImage invocation with the parsed image Hash as the operand. The invoke hook calls Processor#inline_image.
