- disable undo for user preferences (every click would do push an undo), was noticeable on large files.
- also netbeans project file generator now uses branch name for project.

Cycles now uses correct libs on MinGW

Cycles:
* Disable precompiled cuda binaries, always do at run time
* Change preview samples default to 10
* Hide volume panels since they don't do anything yet

Attempt to fix #29200: Camera Tracking Solver

It was an mistake in join tracks operator which lead to reading unitialized memory.

Texturing: texture and 3d view draw type changes, these should only have any
effect for a render engine using new shading nodes. In short:

* No longer uses images assigned to faces in the uv layer, rather the active
image texture node is what is edited/painted/drawn.
* Textured draw type now shows the active image texture node, with solid
lighting.
* Material draw mode shows GLSL shader of a simplified material node tree,
using solid lighting.
* Textures for modifiers, brushes, etc, are now available from a dropdown in
the texture tab in the properties editor. These do not use new shading nodes
yet.

Fix for last fix, guess this compiled ok because it's interpreted as a goto label.

Fix an issue with uninitialized memory

Cycles: svn merge -r41627:41650 ^/trunk/blender

Nodes: add cycles shader nodes, these will only be available to render engines
that use the new shading nodes system. Documentation:

http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes

Code cleanup: fix compile warning.

Fix: incorrect use of IFACE_ macro, and correct a typo.

- Fixed typo in KLT description tooltip
- Fixed inconsistent data type used for pts number in ffmpeg_fetchibuf
and stored in timecode structure. Not really issue for "correct" movie files,
but probably can help for "broken" one

Fix a typo in building undistorted proxies for movie clips.

Thanks Campbell to point on this issue.

use some more logical BLI math functions & tracking used INT_MAX on a short.

Code cleanup and small fixes:

- Assume all areas are using valid MovieClipUser when using functions from movieclip.c
- Set active scene clip to movie-related nodes in compositor rather than checking
if there's only one clip in datablocks
- Fixed users count issue when solving camera motion

Tracker:
* Typo fixes for space_clip.py, patch by Mike S on the mailing list.

Code cleanup - reshuffling some stuff to avoid buildup of long functions in transform code again

correct merge error
