Refactor:
* Draw pressure is handled in stroke level.
* Anchored brush drawing is correctly handled outside sculpt mode too.

Merge from trunk, r57616 through r57877.

Drag dot strokes for image painting.

This was mostly working with undo code.

There is a tradeoff between doing undo traversal for images vs undo
initialiatio time:

The more area the user paints on, the more undo tiles are added to the
system. That makes restoring of the image slower after each step.
A way to optimize this is to completely delete the undo tiles after each
step. This also will make the undo steps use less memory.

However given that for a realistic, non-user-testing use case, the dabs
will be localized, better optimize the initialization case. In
projective texturing, which is the most performance hungry, indeed this
helps with performance, provided the use case is sane. I left the
clearing code ifdefed out just in case.

Also exposed anchored stroke options. They work with texture coordinates
well but not with paint brush size yet.

Merge trunk -r57861 into soc-2013-paint

Sampling for image painting:

Modify the algorithm so that in 3d viewport, it first attempts to sample
the color from the texture assigned to the picked face, if any. This
solves the issue of getting a darker colour than the one requested,
usually due to viewport shading.

=== OpenVDB 1.1.1 added ===

Necessary CMakeLists.txt files edited and created, and core OpenVDB files added to extern/openvdb.

Although probably platform-specific, I needed to add macro definitions to externopenvdbinternalopenvdbmathCoord.h and externopenvdbinternalopenvdbioCompression.h for everything to compile on VS2008. Will revisit this at a more appropriate time.

A more detailed description of the process will be available here: http://wiki.blender.org/index.php/User:Jehuty/GSoC_2013/Discussions/Compiling_OpenVDB

Group instances now update their base objects' level of detail temporarily from their own position. This allows group instances to behave properly with levels of detail.

Removing an unnecessary vector copy when updating levels of detail.

Duplicate objects no longer share level of detail settings.

svn merge ^/trunk/blender -r57381:57829

implementation of the method to rotate the coordinate differentials

The 3Dview now redraws on changes to level of detail settings. Also, changing the distance values on levels of details now causes the levels of detail to be sorted.

Fixing a crash that occurred when give_current_material was passed a NULL object.

Fixed a crash that occurred when an object being used as a level of detail was deleted.

Fixing a minor memory leak caused by not freeing the level of detail list when an object is freed.

Removing a level of detail now causes the view to update. Also making sure to free the removed level of detail now.

Implementation of the system of equations for the deformation with preservation of detail.
Calculating the implied rotation for differential coordinates

Necromancy exercice no #$%^&@!**#$>:3. Resurrect feature from old GSOC
onion branch that applies gravity after each dab in sculpt mode. I am
not very fond of the result, it will need artist feedback and testing.
