Merge branch 'master' into wiggly-widgets

Move widget drawing at a higher level - try drawing on top of rendering
too.

Rationale - widgets might be useful to have even on rendered scenes -
we'll have to see about how this will work

Also use area initialization code to register region specific widgets once.

Conversion functions from/to hair shape keys to particle data.

Shape key infrastructure for hair.

Fix release comfirm for central widget in transform operator

Fixes to highlight code, now widgetmaps remember last active widget and
reset accordingly.

Improved child hair curling for interpolated child particles.

The curl radius for children in interpolated mode was calculated using
the total offset from the parent particle. This leads to very large
radii when the distance is large due to sparse parents. Such behavior is
also very unrealistic because the curl radius is mostly constant and
defined by the material properties.

All the child hairs are roughly parallel by default. To simulate the
agglomeration of children into hair wisps the "flatness" parameter is
now used to clump them together.

Highlighting for manipulator widget.

This should use an "active" system, similar to buttons to detect if last
widget has changed and act accordingly. Currently, when the active
widget changes, there is no change in highlights.

Tidy up the widget API, only do 3d intersection on widgetmaps that
support it (determined during creation)

Widget API:

Code that handles 3D object intersection via GPU selection. We might
want to use raycasting here, but leaving that for when we have it.

Manipulator code now uses this API to do intersection testing

Refactoring of manipulator code to use selection evaluation and codes
that can be shared with other widgets.

Cloth solver data for edit mode is unused, removed it.

WIP code reshuffling for widgets

Manipulator now uses the widget system (no operators used).

Widgets use a similar notification system as operators. It might be
worth using WM_BREAK messages like the rest of the handlers. For now
this should do.

Move manipulator handler to the widget system.
