WidgetGroup now handles updating the manipulator properties.

Still not hooked new arrow widget to the system

Add python exporter that exports a mesh in a C file in a renderer-ready
format (vertices + normals + triangle vertex indices)

This will allow us to create widgets in blender instead of defining them
programmatically.

May also support facegroups for different colors in the future though
they must be somehow tied to the UI colors.

added new setting for fracturing with particle sources, in most cases you want to use the particle
birth coordinates as pointsource, but you can override this to get the coordinates of the current particle simulation state. But as the particle cache is kinda broken and shows wrong positions at beginning if simulation has been run before, this can lead to errors. Best practice is to keep this option enabled, only disable if you really need to !

Enable depth testing for widgets.

Especially if we have many widgets on screen, sorting them will be
difficult and for mesh-armature widgets it will be unavoidable if we
want to avoid tweaking "back" surfaces.

Merge branch 'master' into wiggly-widgets

cleanup: removed unused code and quiet some warnings

crash fix for fracturing with particles, missed proper initialization of voro++ interface struct (in case no computation takes place we need to zeroize the structs in the array though) and usage of particle_state instead of particle_birth coordinates, to be able to use particles not directly at birth position (after particle simulation has run a while)

Fixes to loop mapping code. Looks like UV transfer is starting to look better ;)

First hooking of transfer data and geom mapping for polys and loops.

Using UVMap as test subject. Not even half working yet, though.

Complete shaded arrow widget code. It will need sorting if keep the
shading.

WIP redesign of the system. Nothing functional (not even manipulator).

There is first code for display of an arrow widget. The manipulator will
use those when they are ready.

Basically the manipulator is now a WidgetGroup. WidgetGroups are a new entity and
they manage a group of related widgets. They should be responsible for state update,
drawing and polling of their widgets and can be bound to specific rules.

There is a big design plan on a whiteboard beside me, it will take a few
big commits still to take shape though. One thing at a time, I am first making
reusable arrow widgets that will allow us replace the translate widgets properly.

There are a few reusable widgets planned, more to come later.

Merge branch 'master' into soc-2014-viewport_context

Preliminary commit for simulation preview.

crash fix for: appending objects with fracture modifier from library blends without their respective scenes and attempting to fracture then to build up the modifier structures

Merge branch 'master' into mesh-transfer-data

Dragging the light handle will now point the lamp to the point in 3D
where user is dragging over.

Merge branch 'master' into wiggly-widgets

Merge branch 'master' into dyntopo_holes

enum instead of #define for cloth vertex flags.

Removed accidentally committed debug print.
