OT/NT Refs: Development log, entry #5

Completed

• Added layers (Quotations, Allusions, and Possible Allusions are all on separate layers, independently controllable (see below), as are the book arcs);
• Added panning (click-and-drag to move);
• Added keyboard event handler (to toggle visibility of layers (“q”/“a”/“p” for 3 link layers, “b” for book arcs, “c” to recenter view*, and “r” to reset view to initial state*);
• Added zoom ("+" and “-” to zoom in and out, respectively)

ToDo

In priority order:

• Add book labels
• Fix intermediate point calculation
• Post code to Github
• Add basic interactivity [zooming & panning]
• Add advanced interactivity [to show links for a specific book (a la http://www.nytimes.com/interactive/2007/12/15/us/politics/DEBATE.html)]
• Add columns for each chapter (why?)
• Add mouse scroll wheel zoom handler
• Add the allusion links and possible [allusion] links
• Set up correct Z-order (handled by order of function calls)
