Some enhancement to how plane size is computed. Now you have three choices (absolute, to directly specify the result height, and dpi or dpbu [dots per Blender Unit], to use image definition). Based on an idea and code from mat ali, thanks!

Also fixed correct use of overriden context (not really a bug, but printed annoying warning messages in the console).

MHX importer: the idea to use rna props did not pan out, because it lead to errors when a saved blend file with an mh character was reloaded. Fixed that.

Added support for new visemes and removed export of old faceshapes. Also fixed MH alpha 7 compatibility.

AnimAll: Inserting keyframes on lattices now works in edit mode too. Requested by Virgilio Vasconcelos @ BlenderPro!

un-modified, my own change didnt match up with the x3d spec.

by Michalis Kamburelis (kambi)

Normalize the axis before writing to avoid small values writing as a zero'd axis.

from dan grauer (kromar)

With change use_map_color_emission (which is for volumetrics only) to use_map_emit.

also ignore generated face-images (which have no file path).

   I also updated the Wiki page.
2. There was a small mistake introduced by the last commits. This has been 
   fixed.
3. Code cleaning

according to the "Style Guide for Python Code" 
(http://www.python.org/dev/peps/pep-0008/) and the recent review
(http://codereview.appspot.com/6815052). Some slight changes were done, too. 
Extensive tests have shown that the code is still well working.

Apparently internally SVG importer was using 90 points per blender unit,
not per inch. This made files importing with unexpectable dimensions
which could be really harmful if you're importing blueprints as references.

Now SVG importer is using 90 points per inch, which makes imported files
has correct dimensions in both Metric and Imperal unit systems.

However, there's one possible downside -- imported files would look
smaller in blender units system.

panel from the import/export addons. This means that the panel has had to be 
removed also from the PDB importer/exporter. This is what I have done.

Attention, this is a major change of the Atomic Blender PDB importer/exporter!

A lot of test today have shown, that the new version of the PDB 
importer/exporter has not lost its stability. In the next days, I will perform 
other stability tests.

Also in the PDB IO: relict from old times, which has been removed
