*ray<->bb hit optimization... just to make it "slightly" faster :P

Based on Tactical Optimization of Ray/Box Intersection, by Graham Fyffe
[http://tog.acm.org/resources/RTNews/html/rtnv21n1.html#art9]

*for now it breaks shrinkwrap or other stuff that relies on sphere-raycast of BLI_kdopbvh.

2.5 RNA:

* Tooltip updates by William Reynish. Thanks!

Started operator registration with python. This is a piece of cake!
Made space_script header area customizable with python - need Brecht to
check this.
Added a base for operator registration: a menu in Scripts Window with
two items "Reload Scripts" and "Export". The former will do guess what?
The latter will be populated with submenu items each corresponding to
an exporter :)

2.5

Added search-browse to the Python ID template. Also added icon/button
for 'Add new'. (Note, we need icon for it).

Also fixed bug in search menu closing too quick on mouse-release, when
mouse was close to bottom of menu button.
And removed annoying warning if ID pointer was zero.

2.5:

* Fixed some RNA properties Ranges.

*Instance support at dupliverts/faces
*Octree works nicely on hierarchic trees
*the old code was quite destructive at the Isect variable
changing isec->start, end, vec..now it only changes isec->labda (and hit results)

Currently rendering a BVH of all objects, where each object has it own octree.

Pass context to the "invoke" operator method.

"invoke" should have three args now: self, context and event respectively.

Bugfix for [#18911] Applied torque breaks rigid bodies in game engine

sequencer patch from Xavier Thomas
- allocate transform and crop on "use"
- bring back the scopes drawing (histogram, vectorscope, luma)
- tweak properties layout (need more)

NLA SoC: RNA Fixes

- Lower bound for start values has been expanded to -MAXFRAME, to avoid clipping problems when the strip is moved past frame 0

- Removed some obsolete (+ commented out) NLA wrapping in Object stuff

Allow defining string property on py operator - a first step towards
interfacing the file selector :)

== SEQUENCER ==

This fixes
* some issues with Scene strips containing audio by removing
the curpos pointer from sequence structure. (the same scene
strip can now be used in a row)

That also makes the code a lot cleaner.
* fixed a corner case on the beginning of a strip, where audio was
not mixed in, depending of current audio buffer state.

* Also: made some hardwired variables macros to enhance readability.

Problem remaining: mixing the same scene strip several times (read
put it into a stack instead of into a row) has
problems with HD-audio since the same HD-audio state structure is
used and therefore the system will seek permanently, which leads to
audio distortions...

update from Aaron Keith, fixes normal flipping

Sound actuator bug reported by zapman on blenderartist.
Negative events would play on an actuator if it hadn't played a sound yet.

NLA SoC: Channel ordering change

In response to user-feedback, I've changed the order in which channels appear. Now, the channel ordering is:

- Object/AnimData block
-- Active Action
-- Last NLA Track
..
..
-- First NLA Track

It is important to note several things still:
1) Active action is applied AFTER the NLA Tracks have been evaluated, not before
2) In this new order, the tracks+active action are shown in the evaluation-stack order, i.e. first thing applied is at the bottom, last is at the top.

As a result, I've switched the view-orientation back so that it works the same way as for DopeSheet/Graph editors (i.e. expands downwards not upwards). This may cause problems loading files saved with older builds of this branch. There are still some lingering problems due to this change which I'll fix in due course.

NLA SoC: Operator for adding new NLA-Tracks

New tracks can be added in the following ways (with the mouse hovering over the channels-list):
* Shift-A - this will add a new track at the top of the stack (i.e. above all the existing NLA-tracks but below the Active Action) for every AnimData block where there was a selected NLA-Track

* Ctrl-Shift-A - this will add a new track above every selected one

NLA SoC: 'Split' Operator (YKEY)

Selected NLA Strips are split into two strips, each with half the length of the original strip.

Possible improvements subject to demand:
- multiple splits?
- splits with variable spacing? (i.e. 3:2, or 1:5).

NLA SoC: Evaluation bugfixes

* Strip scaling was being evaluated in the wrong way, resulting in scaled strips not being played too fast (for lengthened strips) or too slow (shortened strips)

* Also, verified that the 'reversed' option works correctly (no changes needed to be made here)

patch from Xavier Thomas, color balance and proxy access both need to allocate structs when enabled.

2.5:

* Wrapped FFMpeg in RNA (some properties are disabled for now).

* Some Texture panel tweaks by William. Thanks!
