Blender Git Loki

* Added the ability to toggle visibility/renderability for modifiers, from the outliner

soc-2008-mxcurioni: Added first batch of Iterators: AdjacencyIterator, Interface0DIterator, CurvePointIterator, StrokeVertexIterator, SVertexIterator, orientedViewEdgeIterator.

* A bit more precision in the bevel mod 'width' field

BGE patch: Add PyDoc for new logic bricks, set exception message on Py error, remove args on Py functions that don't take any to save CPU time

Refactor: Renamed text tool methods (suggestions and docs) for clarity and consistency.

Improvements to text find (and replace):
- Added GUI panel
- Selected text is copied to "find" field
- Option to search "all texts"
- Option to replace text
- Alt+F finds, Ctrl+Alt+F finds again (without UI)
- Alt+H replaces (UI), Ctrl+Alt+H replaces again (and undo works)
- Fixed: Find didn't push undos so cursor position was wrong

time_t isn't supported in SDNA so we'll use double instead. 56bit precision is plenty for storing seconds (for a billion years at least)

Added NodeUpdateGS so GameObject Python api alignAxisToVect function,
Otherwise the rotation isn't applied.

Bugfix: Deleting backward selected text was getting stuck on redo.

Selections were not correctly preserved through undo/redo operations causing unexpected behaviour.

== Grease Pencil - UI Improvements ==

Based on user feedback, I've made some changes to the Grease Pencil UI (most notably in 'Time Editing' facilities).
* 'Edit Timing' button gone
* Pin button and '<Grease Pencil Data' string gone from Action Editor
* Action Editor in 'Grease Pencil' mode now displays all grease-pencil datablocks for current screen.
* AE: GP-Datablocks are drawn like 'groups', with an expand/collapse button to show/hide layers. Its name shows the type of space it comes from, and shows indicative status info (i.e. for 3d-view, it shows view-angle)
* Added refresh calls for action editor after editing relevant data.

I haven't tested all tools yet, but most should be stable.

Also, I've removed some unnecessary buttons, and added a few tooltips. There's also some experimental code to try to get clearer indication of 'active' layer.

soc-2008-mxcurioni: added Iterator class, base class for all iterators in Freestyle (on the C++ side). Created the equivalent in Python BPy_Iterator with the simple interface:
- getExactTypeName()
- increment()
- decrement()
- isBegin()
- isEnd()

Contrary to previously stated, I am reverting back to implementing iterators in the (Python) API, for different reasons:
- it will make testing quicker to achieve, as I won't have to recode a big chunk of the original Python files
- it will be a base for API refactoring
- it won't prevent the use a list-based approach later (it is simple to get it from the Iterator)

soc-2008-mxcurioni: renamed all Freestyle API related files with 'BPy_' prefix to avoid library name collision.

Included MediumType's initialization at proper time to avoid Blender's crash.

== Sequencer ==

Fixes: [#17315] Sequencer: after undo there's no active object
closes: [#17357] fix for bug #17315 - Sequencer: after undo there's no active object
(kiemdoder: thanks for the patch, had to do it in a little bit different way,
since sort_seq will kill your sort order idea...)

soc-2008-mxcurioni: merged changes to revision 15705

soc-2008-mxcurioni: implemented (without testing) StrokeShader, Stroke and MediumType (used by Stroke to define medium types) classes. The Stroke class is missing the InsertVertex method.

Before porting other classes, I'll resolve the List (Python) <=> Iterator (C++) correspondence problem by implementing a general class appropriately suited for the task.

Updated some out of date documentation of Object Ipo curve names

BGE patch: Add min/max parameters to orientation constraint actuator

The min/max parameters define a minimum/maximum angle
that the object axis can have with the reference
direction without being constrainted. The angle is
expressed in degree and is limited to 0-180 range.
The min/max parameters define a conical free zone
around the reference direction.

If the object axis is outside that free zone, the
actuator will tend to put it back using as a temporary
reference direction the vector that is exactly at
min or max degree of the reference direction
(depending if the axis angle is below the minimum
or above the maximum) and is located in the plane
formed by the axis and the reference direction.

With a low damping value, this is equivalent to
clamping the axis orientation within min/max degree
of the reference direction.

Backward compatibility corresponds to the absence
of free zone: min = max = 0.

Update MSVC project files

First draft for control bones repositioning.
All bones marked as no deform are repositioned after the retarget based on their "linked" bone (linked bone is constraint owner if control bone is a target, parent bone if not).

Arithb:
Function to make a quat between two normalized vectors

BGE patch: update KX_GameObject::getChildren() to use CListValue instead of python list (allows name search keep refcount consistent)
