==SCons==
*remove double WITH_BF_FFMPEG

reverting default location for OpenEXR to the proper default
(the one in doc)

==SCons==
* Changing linking order of a few libs, hopefully it solves a unresolved issue.

Adds ffmpeg-support on Linux-platforms. Since ffmpeg is installed
always statically (you have to force it to build a dynamic library) the
resulting binary is redistributable.

The code is made ffmpeg-version independent using #ifdef's.

Appending a single object with particle system, will now also expand to
append its group and objects.

Adds a VFAPI-Plugin for TMPGenc to connect to the blender frameserver.

- Header changes to support hdaudio, memcache limitor and framecount boost.

Base library to support hdaudio-tracks (using ffmpeg only for now).

* Adds configuration buttons for ffmpeg-output
* Large sequencer rewrite to support:
- Audio-tracks, which are not completely loaded into memory (hdaudio) but
kept on disk instead.
- A dependency tree, that builds only the Imbufs, that are really needed
- Cleaner sequencer code
- Per instance data in sequencer plugins (without this, the Dynamic
Noise Reduction plugin would be impossible)
- A Luma Waveform display
- A U/V scatter plot display
- Memcache limiting in sequencer
- Buttons changed according to the boosted framecount limit

==SCons==
* Add WITH_BF_FFMPEG to scons system. Needs to be added to (platform)-config.py
still. Otherwise defaults to 'false'.

* Add memcache limitor-support to imbufs
* Add ffmpeg-read support in anim.c and util.c
* Makes ImBufs refcountable. You can now increase an internal refcounter
in ImBufs (using IMB_refImBuf) which is decreased by freeImBuf.
This makes it possible to simply pass ImBuf pointers around in the
sequencer saving a few memcopies.

* Adds userdef-types for memcache limitor and frameserver-rendering
* Boosts the blender frame limit by changing the type of the frame number
from short to int everywhere. Without this, timelines longer than a few
minutes are impossible to handle.
* Adds several types for ffmpeg input/output, hdaudio-tracks in sequencer

* Fixes memory leak in pipeline.c
* Makes the render pipeline work in arbitrary order to support frameserver
rendering.

==Python API==
Bugfix #3849: "break" instead of "continue" caused memory corruption in
faces.extend() if an edge was given in the middle of parameter list.

FFMPEG-render support.

Enables sequencer ipos for effect plugins and audio-tracks
to be locked to frames instead of the range from 0-100.
Comes very handy on long timelines...

Adds support for frameserver rendering to blender. This is done by
integrating a mini-webserver (around 300 lines of code) into blender.
Using the VFAPI-plugin in contrib/windows it enables blender to
directly feed its output into TMPGEnc, a commercial high quality MPEG-Encoder.
Since it is a mini-webserver, you can probably easily use it for other
interfacing purposes.

Add several usefull sequencer-plugins:
- color-correction-hsv & color-correction-yuv
Do color correction in HSV or YUV-space, rather sophisticated but slow.
You can control setup, gain and gamma and saturation (seperated by
shadows, midtones and highlights).
- gamma
a simple RGB-Gamma plugin, but very fast.
- dnr
Dynamic Noise Reduction (plugin ported from VirtualDub).
This helps mpeg encoding alot, by ignoring noise /movement
below a given threshold between frames.
It is also a lot faster than the original VirtualDub-plugin preserving
it's quality.

Adds for additional buttons for the new sequencer code to distinguish
the display of timeline, output, U/V scatter plot and Luma waveform.

Adds generic memcache limitor (used by the new sequencer to cache
only a certain amount of frames).
