Fix for [#35352] Freestyle + Geometry Spatial Noise freezes on render.

SpatialNoiseShader, as well as SmoothingShader were not updating stroke length after
geometry modification, causing an infinite loop in Stroke::Resample(int iNPoints) due to
incorrect length-based resampling of stroke vertices.

Fix #35368:
* Editing number of segments for particle hair did not update the viewport.
* Hidden particles were confusing, the paths were drawn but without the points.
Now it draws the path faded to indicate that they are hidden/locked.
* Select tips/roots operators now have options to select/deselect/toggle/invert.

Fix #35372: sculpting/painting long brush strokes with small brush size would
take up a lot of memory.

The operator was recording an array with all stroke points. However this was not
particularly useful, only sculpt mode had exec() implemented to redo the stroke,
but it was not registering the operator anyway so there was no way to access the
data after the operator was done. So no one was using this anyway.

I did now implement exec for the paint modes so you can call the operator with
stroke points from a script.

Fix #35355: 2D image paint View mapping mode was dependent on zoom, this was
wrong, it should just fit the texture in the brush circle.

Code cleanup / Cycles:
* Some simplification of closure code (Velvet and Toon).

bmesh, grid fill tool.

This uses 2 edge loops and fills them with a grid, taking into account curvature of surrounding edges.

Fix #35376: node editor throwing python error on some files saved with 2.66 test builds.

Fix cycles CUDA error with world multiple importance sampling, after recent OpenCL fixes.

Fix action zones not drawing properly while sculpting, due to recent bugfix.

Partial redraw doesn't work so well with these, now I've changed the action
zones to just draw as part of regions instead of as a special overdraw done
at the end, which fits better with partial redraw by avoiding any special
exceptions.

Fixes for blender internal viewport render:

* Particles did not render at viewport resolution like meshes.
* Properties editor preview render of hair was crashing, solution is to have
two separate flags for this preview render and viewport preview render.

Fix for missing finalization of memory blocks allocated in the Freestyle module.
Suitable for inclusion in 2.67a.

Libmv internal compiler error workaround for VC2012.
Will be reverted as soon as the x64 compiler is fixed.
For now it shouldn't have an impact on tracking performance. My test have shown no significant speed difference to official VC2008 build of 2.67.

use bool arrays rather then char for weight paint lock/select arrays

Attempt to fix #35057 and #35372: slow texture painting performance.

After the paint refactoring for 2.67, the OpenGL texture was getting updated for
every stroke point, rather than once for every redraw. With a small brush radius
and low spacing the number of stroke points can be quite large, which might have
a big performance impact depending on the graphics card / drivers.

Also for 2D image paint, avoid redrawing the button panels and properties editor
during painting.

There is another possible cause for slowdowns with 3D texture painting which was
not fixed. Projection painting is creating and destroying threads for every stroke
point. Depending on the CPU/OS there might be a lot of overhead in doing that if
the brush size is small.

Fix another cases where painting long brush strokes with small radius was slowed
down, this time by the operator properties getting converted to a string for
display in the info window.

With 1000+ stroke points this can get slow, and takes up too much space anyway,
so now it's (somewhat arbitrarily) limited to printing only 10 points.

Fix slow resizing of ID property arrays with more than 1619 items, it incorrectly
reverted to sizing with by 1 each time. This was slowing down painting long strokes
with small brush radius.

Fix #35354: dyntopo - materials and UI display issues

Textured dyntopo draw was leaving 2d textures enabled when it shouldn't.

Root of the issue was figured out by Campbell, actual place where
2D textures left enabled found by self.

Also, simplified fix is suggested by Campbell (mine was 2 lines longer! :)
