- A file read for opening is laid out in the composite fonts registered
then. Opening a document and reverting the front one now measure again
the type set in a font named like a composite font that an open document
defines, the font database holds or the session registered earlier. Type
in other fonts, missing ones included, keeps the bounds it was read with.
- Switching to a document or closing the front one measures again the type
set in a composite font whose definition changed, and any type without
bounds.
- A document reverted while in the back measures its type in composite
fonts when it comes to the front, not in the front document's.
- Text holding an inline graphic whose symbol's type was measured again
takes the graphic's new size.
- A failed or panicked command puts the font database's composite fonts
back with the documents.
- Setting a composite font to the definition an export lends keeps it after
the export ends.
