/*
* The idea is for the FE to create and fill in one of these
* structures, and then pass it to layout when creating the
* DocumentContext. The document context will keep
* a pointer to this structure, and use the functions in it to
* interface with the FE. The fe_context which is the first parameter
* of each of these functions, is the opaque object that the FE will
* use to determine which window this command is directed at, the fe_context
* object is passed as a separate value to LO_CreateDocumentContext() so
* that multiple fe_context objects can share the same fe_functions
* structure.
*
* Eventually this should be replaced with a JMC interface.
