Merge branch 'master' into wiggly-widgets

Fix crash with widgetgroup

lost instance of transform manipulator

Merge branch 'master' into wiggly-widgets

Bring back the old manipulator code, it works better with the transform
system for now. Backup the old code in a new file

Borrow transform system interaction: When arrow direction has direction
close to view direction, use up/down movement of mouse to calculate
offset.

More refinement to the widget system. Now camera widget should be
indistinguishable than the displayed widget (might probably be worth
deleting the original)

Arrow Widget:

Create a cross style widget, with wireframe cross.

Allows setting a custom scale for the arrow widget also, an up
orientation.

Add flag so widgets only draw on mouse over.

Camera widget now uses this, also now they only draw if limits is on.

Arrow widget interaction:

Fix interaction when pivot is beside the camera. basically we now do all
calculations in 3D space and we do not scale correct the offset in 3D -
this creates a nasty dependency loop between drawing and calculation for
widgets bound to properties - ie offset depends on scale but scale
depends on screen position - ie offset.

Also added an extra callback to get the final position of the widget in
3d space and use that to calculate the scale. This takes care of
bringing a close to the camera widget to the background and the widget
keeping its initial size. The final position can be different from the
initial position, especially when the widget is offset from the original
position.

More info for widget undo push string

Add widget for focus of camera. There are some general issues with
widget scale that I'll fix later.

Conflicts:

Add flag so offset is applied in world, not screen space.

Use better algorithm for arrow widget back transform.

We now use plane/line intersection which seems to work quite well and
agrees to great extent with the transform system as well. There still
some small discrepancy but may also be related to scaling.

WIP cage transform.

This also includes code for the node editor but probably
will try a different use case first.

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.
