* There was no real default value for this parameter (neither "" nor None would work the same as
not specifying that parameter). Now, 'None' is considered as default value, and you get
exact same behavior with this value and if not specifying it. This is important at least for
consistency, and potentially too in some esoteric cases (like generated code or so).
* Add a warning about the fact that 'default' parameter shall not be psecified when items
are given a callback function.
Previous text could make think this func was checking whether a point was
inside and on the face, while it actually checks whether the projection
of that point onto the face is inside its boundary...
Adds bpy.app.sdl to expose SDL version information.
When SDL is not available on a Linux system, certain Blender features
are silently disabled (like joystick support in the BGE). This change
is the first step towards making it more obvious why something isn't
working.
SDL information is exposed to Python via bpy.app.sdl, in the same way
as OCIO and OIIO information is exposed.
Generated system-info.txt contains SDL loading method (linked or
dynamically loaded by Blender) and SDL version number.

- all mathutils types
- only works on frozen data (so vectors can be used in sets/dict keys)
- uses same method as CPython, (matches hashing a tuple)
D1104 by @juicyfruit with own modifications
Added conversion to and from exponential map representation. This
representation is useful for interpolation of > 2 quaternions, or in
PD controllers.
Implementation in C functions quat_to_expmap,
quat_normalized_to_expmap, and expmap_to_quat with Python API, unit
tests and documentation.
Added Quaternion.to_exponential_map() and Quaternion(3-vector) to
Python API.

The original comment seems to suggest that only the rotation vector
is normalized, leaving the rotation angle alone. This is not what happens,
though. The new comment matches the actual implementation, and the
implementation matches what is commonly understood as quaternion
normalization.
Please discuss changes to core mathutils functions first.
Changes like this should be considered and applied to all areas of the API (or not at all).
Missed quaternion, matrix normalize for eg.
A development addon can be used now to enable the debug drawing, without
the need to add UI code for this in the release files.
The SimDebug feature should also get an overall build flag and use
function stubs unless enabled. That way any possibility of overhead in
releases is eliminated.
This module will contain mirrored functions for calculating and applying
weights for points on a mesh. This includes barycentric and UV weighting
and possibly more advanced global weighting such as harmonic weights.
The naming should follow this scheme:
<type>_{2d,3d}_{calc,apply}
e.g.
poly_2d_calc
poly_2d_apply
uv_3d_calc
...

This appends while giving ownership to the list, avoiding temp assignment.
This matches PyList_SET_ITEM which bypasses refcount's
Note, this also reduce code-size, Py_DECREF is a rather heavy macro.
Setting all values of a tuple is such a common operation that it deserves its own macro.
Also added Py_INCREF_RET to avoid confusing use of comma operator.
remove 'type' argument, very few mathutils objects are wrapped,
add new function for creating wrapped objects.
also fixes unlikely memory leak if the data-array can't be allocated.
