e8effb2d0f started whiping cmake into shape for 2.5 still need to figure out
the rna stuff but its close.  Need to get it working for
blender then copy over same to game engine.

bdfe7d89e2 Merge of trunk into blender 2.5:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416

Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
  later added in trunk also, but reverted partially, specifically revision
  16683. I have left out this reversion in the 2.5 branch since I think it is
  needed there.
  http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
  for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
  -W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
  differently. Since this is changed so much, and I don't think those fixes
  would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
  initialized when running with -P. The code that initializes the screen there
  I had to disable, that can't work in 2.5 anymore but left it commented as a
  reminder.

Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.

Still to be done:
* Go over files and functions that were moved to a different location but could
  still use changes that were done in trunk.

8b2811d9d5 VideoTexture: VideoTexture.materialID() can now take texture image name.
You can specify a image name (starting with 'IM') instead of a material
name in VideoTexture.materialID() and return the material ID matching
this texture.
The advantage of this method is that is works with blender material
and UV texture. In case of UV texture, it grabs the internal material
corresponding to the faces that are assigned to this texture. In case
of blender material, it grabs the material that has an image texture
matching the name as first texture channel.
In both cases, the texture id used in VideoTexture.Texture() should be 0.

Ex:

matID = VideoTexture.materialID(obj,'IMvideo.png')
GameLogic.video = VideoTexture.Texture(obj, matID, 0)

ce1625ebc0 VideoTexture: new VideoTexture.ImageFFmpeg to load and reload images.
The FFmpeg library allows to load image files. Although it is possible
to load images using the VideoFFmpeg class, it is not very efficient.
The new class VideoTexture.ImageFFmpeg is dedicated to image management.

Constructor:
-----------
VideoTexture.ImageFFmpeg('image_file_name')
  Opens the file but does not load the texture yet.
  The file name can also be a network address. It can also be a video
  file name; in that case only the first image is loaded.

Methods:
-------
refresh(True)
  Loads the image to texture. 
  You just need to call it once, the file is automatically closed after
  that and calling refresh() again will have no effect.

reload('new_file_name')
  Reloads the image (if new_file_name is omitted) or loads a new image.
  The file is opened but the texture is not updated yet, you need
  to call refresh() once to load the texture.

Attributes:
----------
status
  returns the image status:
    2 : file opened, texture not loaded
    3 : file closed, texture loaded

image
  returns the image data as a string of RGBA pixel

size
  returns the image size [x,y]

scale
  get/set the scale flag. 
  If the scale flag is False, the image is rescale to texture format
  using gluScaleImage() function, slow but good quality.
  If the scale flag is True, the image is rescaled using a fast but
  less accurate algorithm.

flip
  get/set Y-flip flag.
  Set to True by default as FFmpeg always provides the image upside down

filter
  get/set filter(s) on the image.

Example:

a8c4eef326 VideoTexture module.
The only compilation system that works for sure is the MSVC project files. I've tried my best to
update the other compilation system but I count on the community to check and fix them.
 
This is Zdeno Miklas video texture plugin ported to trunk. 
The original plugin API is maintained (can be found here http://home.scarlet.be/~tsi46445/blender/blendVideoTex.html)
EXCEPT for the following:

The module name is changed to VideoTexture (instead of blendVideoTex).

A new (and only) video source is now available: VideoFFmpeg()
You must pass 1 to 4 arguments when you create it (you can use named arguments):

VideoFFmpeg(file) : play a video file
VideoFFmpeg(file, capture, rate, width, height) : start a live video capture

file:
In the first form, file is a video file name, relative to startup directory.
It can also be a URL, FFmpeg will happily stream a video from a network source.
In the second form, file is empty or is a hint for the format of the video capture.
In Windows, file is ignored and should be empty or not specified.
In Linux, ffmpeg supports two types of device: VideoForLinux and DV1394. 
The user specifies the type of device with the file parameter:
   [<device_type>][:<standard>]
   <device_type> : 'v4l' for VideoForLinux, 'dv1394' for DV1394; default to 'v4l'
   <standard>    : 'pal', 'secam' or 'ntsc', default to 'ntsc'
The driver name is constructed automatically from the device types:
   v4l   : /dev/video<capture>
   dv1394: /dev/dv1394/<capture>
If you have different driver name, you can specify the driver name explicitely 
instead of device type. Examples of valid file parameter:
   /dev/v4l/video0:pal
   /dev/ieee1394/1:ntsc
   dv1394:ntsc
   v4l:pal
   :secam

capture: 
Defines the index number of the capture source, starting from 0. The first capture device is always 0.
The VideoTexutre modules knows that you want to start a live video capture when you set this parameter to a number >= 0. Setting this parameter < 0 indicates a video file playback. Default value is -1.

rate: 
the capture frame rate, by default 25 frames/sec

width: 
height: 
Width and height of the video capture in pixel, default value 0.
In Windows you must specify these values and they must fit with the capture device capability. 
For example, if you have a webcam that can capture at 160x120, 320x240 or 640x480, 
you must specify one of these couple of values or the opening of the video source will fail.
In Linux, default values are provided by the VideoForLinux driver if you don't specify width and height.

Simple example
**************
1. Texture definition script:

import VideoTexture

contr = GameLogic.getCurrentController()
obj = contr.getOwner()
if not hasattr(GameLogic, 'video'):
	matID = VideoTexture.materialID(obj, 'MAVideoMat')
	GameLogic.video = VideoTexture.Texture(obj, matID)
	GameLogic.vidSrc = VideoTexture.VideoFFmpeg('trailer_400p.ogg')
	# Streaming is also possible:
	#GameLogic.vidSrc = VideoTexture.VideoFFmpeg('http://10.32.1.10/trailer_400p.ogg')
	GameLogic.vidSrc.repeat = -1
	# If the video dimensions are not a power of 2, scaling must be done before
	# sending the texture to the GPU. This is done by default with gluScaleImage()
	# but you can also use a faster, but less precise, scaling by setting scale
	# to True. Best approach is to convert the video offline and set the dimensions right.
	GameLogic.vidSrc.scale = True
	# FFmpeg always delivers the video image upside down, so flipping is enabled automatically
	#GameLogic.vidSrc.flip = True

if contr.getSensors()[0].isPositive():
	GameLogic.video.source = GameLogic.vidSrc
	GameLogic.vidSrc.play()


2. Texture refresh script:

obj = GameLogic.getCurrentController().getOwner()
if hasattr(GameLogic, 'video') != 0:
  GameLogic.video.refresh(True)
