Better api use for paths.
Avoid possibly copy past buffer.

Added DNA_DEPRECATED attribute to some old data in bNodeSocket. DNA_DEPRECATED is disabled in writefile.c now to allow forward compatibility code writing to deprecated member data.

formatting edits (<120 line length), remove invalid 'defaults' keyword arg from docs.

Fix [#29940] Stretch To constraint breaks scaling in Transform constraint.

Compute of dist between ob/bone and target was quite odd and causing that bug.

formatted snapquats table so entries line up, rounded to 7 significant digits (fp32 respects ~6), no functional change

tidy up ndof handling code -- whitespace, comments, ndof->rvec[0] to ndof->rx, etc. no functional changes

quiet warnings and possible NULL checking crash fix for indentation functions.

modify number button copy/paste to work as if you enter the button, select text, type into another button the same value.

This means you can copy/paste units and python expressions.

fix 2 bugs
- box packing wasn't flagging out the right free corner of a vertex in some cases.
- tex_space_curve wasn't counting quad displists properly.

Skip subsurf normal allocation/calculation when not needed.

CCGSubsurf has already a function to disable calculation of normals,
but seems it wasn't used. This patch changes subsurf UV and
subsurf_calculate_limit_positions() to not calculate normals, and also
not allocate space for them.

Should be no functional changes, just a small speedup/less memory use
during subdivision for these cases.

use property definitions more consistant with other addons in trunk. (no functional change)

Try fixing modifier keys not working correctly for uv sculpting.

Removed a hard-coded limit that the backbone stretching effect was applied to
stokes with 2D length longer than 50. Problem report by Forrest Gimp, thanks!

Sample as Lamp option for world shaders, to enable multiple importance sampling.

By default lighting from the world is computed solely with indirect light
sampling. However for more complex environment maps this can be too noisy, as
sampling the BSDF may not easily find the highlights in the environment map
image. By enabling this option, the world background will be sampled as a lamp,
with lighter parts automatically given more samples.

Map Resolution specifies the size of the importance map (res x res). Before
rendering starts, an importance map is generated by "baking" a grayscale image
from the world shader. This will then be used to determine which parts of the
background are light and so should receive more samples than darker parts.
Higher resolutions will result in more accurate sampling but take more setup
time and memory.

Patch by Mike Farnsworth, thanks!

Minor fix for socket default value conversion. The switch statement would not break correctly.

svn merge ^/trunk/blender -r43554:43564

minor warning/fixes

comment some dead assibnment and set dummy values for image profile conversion in case of invalid input.

quiet some warnings

quiet warnings for using uninialized color var in ED_image_draw_info().
