Policy	`PDF_MISSING_GLYPH_REPORT` or 0 records the event and removes the missing scalar; `PDF_MISSING_GLYPH_ABORT` or 1 records the event and rejects the operation

Returns 1 for a supported policy and 0 for any other value

An aborted operation sets LastErrorCode to 521

A registered callback receives the policy as its initial action and may override it for each event
