Yet another IK offset fix, pointed out by Ton. Offset should be passed
in local bone space.

-- patch submitted by Johnny Matthews which lets a user get an Ipo curve by
its adrcode in addition to its string name (shape keys don't have fixed
or unique string names, and they are stored in the key, not the Ipo).
This will make it easier to later use constants from dictionaries to
access a curve.

* Gave the Obdata to Center / Center New / Center Cursor
tools a nice little home in the 3D View header/toolbox
transform menu. Death to button-only actions!

Fix: Scaling in Action Window didn't correct for NLA mapped time

Fix: Using Hinge Bones in a chain with "Target-less IK" didn't apply the
correct rotations.

iNew: TimeSlide in Action Window

Usage: press Tkey, and you can proportionally squeeze or stretch the
selected keys, with current mouse position as reference. Only works with
more than 3 keys selected horizontally.

I've remapped the old Tkey (ipo type) to SHIFT+T... might be temporal, I
have an idea for a cool 2D manipulator system that makes it much friendlier
to grab/scale/slide keys all in once.

Also: fix for HOME key in action editor (didn't do Pin), and removed gcc
warnings from jiri's commit in editmesh_add.c

-- one step closer to fixing booleans: one-line change to use new object
instead of original object when building new mesh and mesh material list

Removed key.getChannelIpo() doc.

Removed key.getChannelIpo() since it is not proper implementation anymore.

Fix for HOME key in Action Window. Didn't check for mapped NLA time yet.

Two half working commits!

- Python Drivers
In Ipo Window "transform properties" Panel, added the buttons, and the
initial handling (now only printing text). Willian makes it work!

- Better Matrix to Eul, code submitted by Brecht. No time yet to do it
really nice (like a Mat3ToEulCompat(mat, eul, eulc))

-- fix (I think) for "normal booleans interface (for Wkey 123 entries)";
second selected object's mesh was being overwritten by new object's
mesh, so new object had no empty mesh

A few leftover py2.3 -> py2.4 changes:

- updated python24.zip to include all required module dependancies.
- updated zlib.pyd to py24 zlib.pyd - now it opens the zip file (thanks ianwill!)
- removed whrandom module from basic_modules (deprecated in py24)

- bug fix: normal of new added face is calculated without mistakes now
- direction of face normal doesn't depend on user's view to scene anymore,
it is influenced only by direction of face normals in nieghborhood

Support for adding elements in random positions in an opennl matrix.
Also some code formatting.

Previous change to enable Shape Actions, didn't support Drivers yet.

-- testing a patch which lets Python initialize the site path for Blender
(old code is just "#ifdef"-ed out for now.)

Please give this a try on all platforms and give us feedback on what you
see for your sys.path setting in Blender (run these two lines in text window)

import sys
print sys.path

Mirror clipping bug; Martin used abs() which is for int! should be fabs().

-- fix compiler warning about return "from incompatible pointer type" when
returning Python exceptions. EXPP_ReturnPyObjError() always returns a
NULL because Python expects error conditions to return a NULL pointer
instead of an object. Since the pointer is cast to a PyObject *, it's
ugly to use for propagating the errors back in this case, so this fix just
uses PyErr_SetString() to set the error and return NULL (see the body
of EXPP_ReturnPyObjError() ).

Two new IK features.

1) Target-less IK

If you add an IK constraint without a target set (no object or bone target),
it now can be grabbed and moved with IK, using its own Bone tip or root as
target itself. This way you can use IK for posing, without having the IK
executed while it animates or while a Pose is being solved for real IK.

After grabbing "Target-less IK", it applies the resulted motion in the
pose-channels, which then can be used to insert keypositions.

The Target-less IK bone can still be rotated without IK, also its chain
can be edited as usual.

UI: The CTRL+I menu gives this as an option too. In the 3D window it is
drawn with orangish color.

Note that IK is not resistant to non-uniform scaling yet.

2) Auto-IK

When the option "Automatic IK" is set, in Edit Buttons Armature Panel,
it creates automatic temporal Target-less IK for the Bone you grab or
translate.

The rules are:

- it only works when a single Bone is selected
- if the Bone is a root bone (no parent), it adds IK to the end of the
chain(s)
- otherwise it adds the IK to the active Bone
- the temporal IK chain only consists of connected Bones.

This method is still a bit experimental. Maybe it should become a special
grabbing option (like SHIFT+G in Pose Mode). It also only works OK for rigs
that fit for it well... when a rig already is fully setup with IK it can't
do much good. :)
