Implementation of a target density feature for the hair simulation.

This allows setting a target density which the fluid simulation will
take into account as an additional term in the pressure Poisson
equation. Based on two papers
"Detail Preserving Continuum Simulation of Straight Hair" (McAdams et al. 2009)
and
"Two-way Coupled SPH and Particle Level Set Fluid Simulation" (Losasso et al. 2008)

Currently the target pressure is specified directly, but it will be
a lot more convenient to define this in terms of a geometric value such
as "number of hairs per area" (combined with hair "thickness").

Another fix for off-by-one hair grid resolution errors.

Rewriting the grid rasterization function for hair segments.

Draw actual hair keys when the "Guide Hair" setting is enabled.

Without this certain debug tasks become very hard to visualize.

Change widget interaction slightly so transform works immediately.

It may be better to use transform code for widgets but this will cause
nested operators for widget/operator and needs some consideration.

For transform e.g. we would have one transform operator taking care of
transformation of the widget, then feeding this back to regular object
transform.

Fix incorrect wrapping of lamp to RNA for widget.

Remove magic numbers

Widgets: inverted/constrained to property range working for properties
(not operators yet).

Now "umbrella" widget type works correctly.

Includes minor cleanup of view3d widgetgroup routines.

correct offset for scaled widgets during interaction

Merge branch 'terrible_consequencer' into gooseberry

Snap to left-right based on position of mouse relative to selection.

Support endpoint snapping correctly.

First iteration of snapping based on strips - will be improved based on
imput from Mathieu.

WidgetMaps:

Now widgetmaps get created and destroyed with the area. Not sure if it's
the best design but it avoids too many creations and recreations.

arrow offset now calculated at property binding time - no RNA access
during interaction means no chance of crash during undo.

Bound properties/operators to widgets at draw time. This fits our design
much better (is the same as the way panels work) and will help avoiding
some crashes on undo.

Fix for grid drawing in 3D view, was using one less grid cell.
