===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
Closed regions didn't always draw the (+) icon right place, confusing
for users.
Next to that, I think this icon is using a bad metaphor or visual language,
Illustrated best if you close a header in outliner or buttons. Icons are
UI widgets, for screen/editor layouts different controls can be stylized.
My preference is something that aligns visually to the seperators between
regions; for testing and hacking pleasure I've added two quick versions,
a small tabbish thing and a triangle. Enable these with debug menu,
ALT+CTRL+D, values 1 or 2.
This is simply drawn with opengl now. An image for it can be made as well.
Previews:

There's other design ideas to explore as well, like making region deviders
8-10 pixels wide, with a 'drag me' dot on it or so. That takes some screen
estate though, and will require to add big editor-dividers too...
Fun stuff for the mockup-mafia to check on, we have time :)
most local modifier,GPU,ImBuf and Interface functions are now static.
also fixed an error were the fluid modifier definition and the header didnt have the same number of args.
- move test -> tests, this name is used elsewhere in lib/tests.
- change interface code not to loop on a float value (clang warning), harmless, but with extreme cases an eternal loop would still be possible though unlikely.
+ changed lines connecting nodes:
they now use a linewidth of 1.5px for the light foreground and 4px for the dark background.
this should fix node-lines not being visible on almost black or all white backdrops.
+ muted nodes now also show a red tinted header if they are hidden (collapsed)
+ both active and selected nodes show a (now properly antialiased) highlighting frame
+ fixed a small error in dropshadow code resulting in a gap at borders
+ fixed a tiny error for the collapsing indicators (triangles) - they were not symmetrical.
Ton will add proper theme colors for the node-editor in the coming days.
- made theme colors for mesh edge len & face angle/area display.
- use %g rather then %f for float display, trims unneeded zeros.
- store cached 2d and 3d text color as bytes rather then floats, compare when drawing to avoid setting the context.
- use unsigned char for more color functions, avoids casting to glColorubv().
- pep8 script was giving an error on non utf8 scons source files.
- use PyList_SET_ITEM macro when list type is ensured.
- all mathutils types use subtypes to create new types when available.
- use defines MAT3_UNITY, MAT4_UNITY to initialize unit matrices.
- open operator was incorrectly checking if the font path was set.
- rna ID editable check was also incorrect, checking the ID name rather then the filename.
- use define FO_BUILTIN_NAME rather then "<builtin>".
Both stored the filename of the blend file, but G.sce stored the last opened file.
This will make blender act differently in some cases since a relative path to the last opened file will no longer resolve (which is correct IMHO since that file isnt open and the path might not even be valid anymore).
Tested linking with durian files and rendering to relative paths when no files is loaded however we may need to have some operators give an error if they are used on the default startup.blend.
- made interface, windowmanager, readfile build without unused warnings.
- re-arranged CMake's source/blender build order so less changed libs are build later, eg: IK, avi

The patch renames and moves gl_round_box, gl_round_box_shade and gl_round_box_vertical_shade to UI_interface.h, so the extern usages are not needed anymore.
tile cache code in imbuf, but it is not hooked up to the render engine.
Imbuf module: some small refactoring and removing a lot of unused or old code
(about 6.5k lines).
* Added a ImFileType struct with callbacks to make adding an file format type,
or making changes to the API easier.
* Move imbuf init/exit code into IMB_init()/IMB_exit() functions.
* Increased mipmap levels from 10 to 20, you run into this limit already with
a 2k image.
* Removed hamx, amiga, anim5 format support.
* Removed colormap saving, only simple colormap code now for reading tga.
* Removed gen_dynlibtiff.py, editing this is almost as much work as just
editing the code directly.
* Functions removed that were only used for sequencer plugin API:
IMB_anim_nextpic, IMB_clever_double, IMB_antialias, IMB_gamwarp,
IMB_scalefieldImBuf, IMB_scalefastfieldImBuf, IMB_onethird, IMB_halflace,
IMB_dit0, IMB_dit2, IMB_cspace
* Write metadata info into OpenEXR images. Can be viewed with the command
line utility 'exrheader'

While I was looking in outliner.c, made some changes to let extra passes display
there such as environment (commented out before due to a previous limitation).
Also changed outliner object visbility/selectability/renderability toggles to use
RNA buttons so you can insert keyframes with RMB menu etc.
