This simply mimics code used for loopnormals, to enable py scripts to generate and access (temporary)
a tangent 3D vector and bitangent sign for each loop. Together with the split normals, this allow
to recreate a complete tangent space for normal mapping (bitangent = bitangent_sign * cross(normal, tangent)).
Expects all faces to be tri or quads.

EditFont's use of Curve.len was very confusing, in editmode it
represented the number of characters, in object mode the number of
bytes. add Curve.len_wchar and keep track of both.
Also don't convert the editmode text into utf8 on every keystroke.
Now this is done on exiting editmode or save - to match most other
object types.
This also fixes curves 'body_format' being reported with an invalid size.
This mode is designed for passive 3D TV: the viewport is split
horizontally - left eye above, right eye below - but the original camera
viewport is squashed in each half (with half the vertical resolution).
This is necessary to restore the aspect ratio in the 3D output because the TV expands each half to the full screen size.
Summary:
Crash was happening because of fcurve modifier stack
used modifier's DNA to store temporary data.
Now made it so storage for such a thing is being
allocated locally per object update so multiple objects
which shares the same animation wouldn't run into
threading conflict anymore.
This storage might be a part of EvaluationContext,
but that'd mean passing this context all over in
object_where_is which will clutter API for now without
actual benefit for this.
Optimization notes: storage is only being allocated
if there're Cycles modifier in the stack, so there're
no extra allocations happening in all other cases.
To make code a bit less cluttered with this storage
passing all over the place added extra callbacks to
the FModifier storage which runs evaluation with the
given storage.

The options are:
Base: Base mesh
Deform: shape keys and deform modifiers
Final: All deformations and modifiers
It would be nice to have a way of specifying where exactly in the
modifier stack the collision shape is generated. However this is not
staight forward since the rigid body simulation is not part of the
modifier system and would require hacks to make it work.
It is now possible to display per-frame track reprojection
error in curve view of clip editor. Simply enable corresponding
option in filter buttons.
Currently displayed using blue color which might confuse with
average reprojection error, further color tweaks are possible
and easy.
Also changed icon track x/y curves. Better icons here are
really appreciated.
Summary: Just some extra comparison between native and 32bit structure length was needed.

Levels of detail can be added and modified in the object panel. The object
panel also contains new tools for generating levels of detail, setting up
levels of detail based on object names (useful for importing), and
clearing an object's level of detail settings. This is meant as a game
engine feature, though the level of details settings can be previewed in
the viewport.

Summary:
This commit removes ~10000 strlen calls and ~100000 memcpy calls in blender (profiled with blender --background), ~10000 memcpy calls in makesdna.
There is no need to create null-terminated strings for atoi, because it converts only the initial portion of the string anyway.
Also it was noticed that DNA_elem_array_size and arraysize functions work only with full strings, so there is no point to calculate strlen.

Summary:
Behaves very much the same as cache for Movie Clip datablock:
- Image now have `MovieCache *cache` field which replaced
legacy `ListBase ibufs`.
This allows image datablock to easily keep of image
buffers which are owned by itself. This field isn't
saved to the file and getting restored on undo steps.
However, cache limit is global for movies, sequences
and image datablocks now. So overall cached image buffers
size will not go above cache limit size in user
preferences.
- Image buffers which are marked as BITMAPDIRTY will never
be freed from the cache.
- Added utility function to iterate over image buffers
saved in movie cache.
- Movie cache cleanup check callback now have ImBuf argument
which can be used in a condition of cleanup.
- Added some utility functions which replaces legacy ibufs
iterations with image cache iteration which happens from
inside a lock.
- Fixed `image_mem_size()` which was only counting one of
the buffers if both float and byte buffer present.
Additional notes:
- `BKE_image_get_first_ibuf()` is rather stupid, but direct
access to ibufs->first was also the same stupid idea.
Would consider avoid this function is another project.
- There are some places which doesn't look threadsafe, but
they already were not so much threadsafe anyway before.
So think not a big deal with solving this later.
Finally solves infinite memory usage by image sequences! :)

The trackpad would give isolated mouse pan events with a distance smaller than
one line or character. For other 2D views this is all accumulated in floats,
but in the text editor it only keeps track of integers, and the small mouse pan
events got lost due to rounding.
Now it keeps track of sub-line or sub-character scroll offsets to avoid this.
There were several issues with how bounding box and texture space
are calculated:
- This was done at the same time as applying modifiers, meaning if
several objects are sharing the same curve datablock, bounding
box and texture space will be calculated multiple times.
Further, allocating bounding box wasn't safe for threading.
- Bounding box and texture space were evaluated after pre-tessellation
modifiers are applied. This means Curve-level data is actually
depends on object data, and it's really bad because different
objects could have different modifiers and this leads to
conflicts (curve's data depends on object evaluation order)
and doesn't behave in a predictable way.
This commit moves bounding box and texture space evaluation from
modifier stack to own utility functions, just like it's was done
for meshes.
This makes curve objects update thread-safe, but gives some
limitations as well. Namely, with such approach it's not so
clear how to preserve the same behavior of texture space:
before this change texture space and bounding box would match
beveled curve as accurate as possible.
Old behavior was nice for quick texturing -- in most cases you
didn't need to modify texture space at all. But texture space
was depending on render/preview settings which could easily lead
to situations, when final result would be far different from
preview one.
Now we're using CV points coordinates and their radius to approximate
the bounding box. This doesn't give the same exact texture space,
but it helps a lot keeping texture space in a nice predictable way.
We could make approximation smarter in the future, but fir now
added operator to match texture space to fully tessellated curve
called "Match Texture Space".

Removed USE_HIDDEN_PREVIEW from source code as it is now deprecated.
The feature was introduced during project mango to quickly hide previews, now that the previews are hidden by default this feature has no need.
Inside the DNA the flag is still visible in comment, this way no one will reuse that value as it could have some side effects

- At Mind -
* Move symmetry options to the paint struct (where all paint systems can
make use of it)
* Rename draw_pressure to stroke_active. This is what is really checked
on those occasions that this is used. Also move turning on/off of this
option to the stroke level and avoid doing it on every stroke system.
* Rename BRUSH_RESTORE_MESH to BRUSH_DRAG_DOT. In image painting this
won't restore any mesh, so better have a name that is directly linked to
what the flag actually does.
In the user preferences all node classes can get its own color
The in/out color is splitted into 2 sepatate colors
the rna has been updated to better names
Summary:
Was a limitation of short data type used for id->us.
Made it to be int, needed to reshuffle fields a bit

This is a addtion to the dynamic fly mode.
It behaves as the first person navigation system available in most 3d world games nowadays.
You can alternate between the old mode (Fly) and the new mode (Walk) in User Preferences > Inputs
Manual:

Shortcuts:
----------
WASD (hold) - Move forward/backward and straft left/right
QE (hold) - Move up and down
Tab - Alternate between Walk and Fly modes
Shift (hold) - Speed up movement
Alt (hold) - Slow down movement
Space or MMB - Teleport
V - Jump
+/- or mouse wheel - speed increase/decrease speed for this Blender session
User Preferences Options:
-------------------------
Navigation Mode - fly/walk navigation systems (fly is the old, walk is the new, next options are for walk mode only)
Gravity - alternate between free navigation and walk with gravity modes
Mouse Sensitivity - sensitivity factor to mouse influence to look around
Teleport Duration - how long the teleport lasts
Camera Height - camera height to use in gravity mode
Jump Height - maximum jump speed in m/s
Move Speed - base move speed in m/s
Boost Factor - multiplication factor when running or going slow (1/boost)
Development Notes:
------------------
* The initial code was based on view3d_fly.c.
* The NDoF code was not touched, so it most likely is not working.
Pending Issues:
---------------
* Draw in the UI the shortcut options, and current values (e.g., Mode: Fly/Walk)
(we need a proper API for that)
* OSX seems to present issues if we re-center the mouse every time. We implemented a workaround for that, but a real fix would be welcome.

Summary:
Now it's possible to assign an image to plane tracks
in clip editor. This image is only used for display
in clip editor and this image is being warped into
the plane track rectangle.
Main purpose of this is to get early feedback about
how good image warping matches the footage, before
clip goes to the compositor.
Pretty much straightforward change: just compute
homography from undeformed normalized frame corner
coordinates (unity square) to plane marker corners
and apply this matrix to opengl stack.
Still could improve behavior when perspective
plane transform is degenerate, but that's not so
much critical for now i'd say.

- When existing faces are available use their UV values
- When no faces are connected to an edge - generate UV's
Also add option to stretch U/V to bounds.
This allows you to choose between subdivide edges, collapse and both. Being able to
only collapse edges can be useful to simplify meshes with accidentally introducing
more detail.
