A start on documentation for SvgCanvas using NaturalDocs.  You will need to download the NaturalDocs and put it in svg-edit/naturaldocs
Starter documentation
Correction to Makefile to remove naturaldocs config directory, not docs directory.  Add main index.html doc file for API

Fixing recalculateDimensions() for absolute segments - first pass
Fixing recalculateDimensions() for absolute segments - final pass
Fix Issue 227: Move elements to a different layer.  Also document all of the Layer API functions of SvgCanvas.
Move-To-Layer control now lives in the Layers panel.  Restructured layout of layers panel and added a non-functional handle.  Changed pointer-events to be 'inherit' for all elements inside the layer.  Clear selection after moving elements to a layer.
Make the layer handle draggable.
Fix Issue 270: element selectable again.  Remove setting of pointer-events to 'none' on all children as they all inherit now from the layer
Fix Issue 271: Repair cut error and restore opacity tool functionality
Issue 124: Move copyright out of tools_bottom_3
Made poly points moveable after rotation. Oh yes.
Mostly fixed latest bugs on Issue 118

Fix Issue 274: pasting in text has pointer-events problems
Fix Issue 273: preserve whitespace in text elements
