Detailed Description

An svn_txdelta_window_t object describes how to reconstruct a contiguous section of the target string (the "target view") using a specified contiguous region of the source string (the "source view").

It contains a series of instructions which assemble the new target string text by pulling together substrings from:

the source view,

the previously constructed portion of the target view,

a string of new data contained within the window structure

The source view must always slide forward from one window to the next; that is, neither the beginning nor the end of the source view may move to the left as we read from a window stream. This property allows us to apply deltas to non-seekable source streams without making a full copy of the source stream.
