  the associated screen.

  sheet method in the schematic editor frame object to eliminate message
  dialogs.

  containers.

Pcbnew: fix that prevents loading modules from libraries (footprint name not identified in lib)
Module Editor: Try to fix incorrect printing. Fixed now only for scale 1. Nor working for other scales. (Work in progress).
Gerbview: Known bug: printing not working.
VRML export: Fix incorrect export of 3D shapes rotations when the 3D shape was rotated.

Eeschema: fix incorrect undo behavior after a component edition using the dialog frame (some changes were not undoable).
Fix incorrect behavior after unit selection using the popup menu,  and add undo command after this change (was non undoable)

* Move update block pick list code to SCH_SCREEN object.

Eeschema: cleaning code. Start work to enhance annotation algorithm.
Already added an option to annotate using sheet number (sheet 1 uses numbers 100 to 199, sheet 2 uses 200 to 299..).
Works fine if deleting existing annotation, but needs work to be used when the existing annotation is kept .

Eeschema: in component properties dialog, add control for fields texts justification, like in Libedit.
Fix some Doxygen warnings.

Cosmetic enhancements. Eeschema: in libedit the Value Field is n more editable in the field editor dialog (due to recent changes in library code)

minor cleanup. minor enhancements. Finish file housekeeping. add Bug 682586 fix from Mark van Doesburg.

Eeschema: converted plot PS dialog from Dialogblocks to wxFormBuilder Fixed a minor bug when plotting shapes with filled in background option. Pcbnew: Added locked modules block patch
