inpaint - gain some speed by not doing X/Y clamping in inner loops.
add assert() so we can ensure its not happening still.

- fix incorrect array delete use.
- replace 1.0f / sqrt(2) with M_SQRT1_2 define.
- use mini rather then MIN2.

style cleanup: use this->m_* for private members.

svn merge ^/trunk/blender -r49333:49361

add inline functions for max/min ints, good to use when the arguments are function calls (we had a few of these).

code cleanup:
- building without python works again
- rename maxi/mini to i_max/i_min (so thay are available for function names)
- some minor edits to IK stretch setting (no functional changes).

code cleanup: replace MIN2/MAX2 with minf/maxf

This adds an inpaint node to blender.

In case, you don't know, inpainting does this:
http://en.wikipedia.org/wiki/Inpainting

It's use cases in blender are

* wire removal
* green screen background reconstruction

The node isn't tile based (for fundamental reasons), but very fast,
since it first builds a manhatten distance map and after that performs
color convolution only on the edges.

That's something, one should probably add also to the dilate node (in
step mode) to make it perform a lot better for dilate iterations greater
than 3.

It will bring it's computing time from O(n^3) down to O(n^2).
Take a look here for the details:

Support for depth buffers in compositor and viewer node
Support for only alpha images in compositor and viewer node

code cleanup: assign mode to a variable in the 3d view header and remove some unused imports

Additional fix #32074, by Sven-Hendrik Haase (svenstaro). Boost version header must be included in cycles in order to expand the version check macro.

User Interface Scripts:
* Code cleanup, removed unneeded code.
* Style cleanup, don't break lines to early
(unless marked as pep8-80 or pep8-120 compliant)
* Keep 1 line after layout declaration empty.

Sequel of r49112 (raising average bitrate without min/max ones is a bit useless with vbr codecs ;) ). Used +/- 50% of max average br respectively for max/min br...

Fix for [#32213] "Action actuator doesn't finish playing if frame rate drops" reported by Alex Fraser (z0r). The action actuator was calling StopAction when it's time ran out. Now I'm just letting BL_Action handle stopping. Hopefully this doesn't break something else now....

Fix for [#27484] "Run-time command line options don't work in Multi-texture mode." reported by Josiah Lane (solarlune). The -g nomipmap = 1 option only changed the mipmapping option for bf_gpu, which BL_Texture wasn't checking.

scale down histogram button movement by 10, was very sensitive

Documentation:
* Some UI docs for the Best Practise guide. Still WIP.

fix for own regression with handling of script paths, however this didnt work quite right before either.

Handle these 2 kinds of script paths
* user script path: ~/.blender/scripts OR $BLENDER_USER_SCRIPTS
* pref script path: always bpy.context.user_preferences.filepaths.script_directory

now both are returned by bpy.utils.script_paths()
