Andrew,

In last night's discussion I got a bit derailed about RefWindow
 caching.

(A RefWindow (referential window) is a zz cell that looks
 into a document stored as a file outside ZZ.  We've been
 calling it a Referential Cell, but I think RefWindow says it
 better.)

A RefWindow is defined as a frame which knows its height,
 width, and *where in the document it points to*.

We'll be wanting it to scroll.  So what needs to be cached
 is generally the whole document, not just what appears in
 the window.

(Note: scrolling is being defined for our TPX generator,
 but in general it shd work with other windows as well,
 such as WordPad.)

(For funny-formated doxx, like HTML and Word, I favor
 parsing into our own better-generalized parallel format).

ChrzT
