"Unexisting" particles must be freed after the unexist flag has been set,
which was no longer the case after 78c491e62a.

There are several ways to end up with an object with skin modifier, but no
skin data on the geometry. So we need an operator to add it by hands.
Also tweaked a bit UI of this modifier.
- simplify boundary handling (walk from boundary - no need to reset walking)
- early exit when the vert has >2 boundaries
- use BM_vert_step_fan_loop to walk the fan
When working with a pen only, it was previously impossible to exit Grease Pencil
draw mode (when continous drawing was enabled). Now, clicking outside the drawing region
(e.g. in the timeline, properties editor, or the header/properties/toolshelf regions)
where you are drawing will exit this mode.
Some corner cases to be aware of:
* When Region Overlap is enabled, clicking on the overlapping panels still exits
draw mode (even though you can see behind the buttons)
* In the Nodes Editor, clicking on a node (while in drawmode) will still draw a
dot/stroke. But, you can still exit drawmode by clicking on any of the panels
(properties/toolshelf/header) mentioned earlier
* To cope with cases where the operator is launched from the toolshelf, the
code now sets a new "active region" when the first stroke is performed
(based on what region is under the cursor at the time of that stroke),
overwriting the setting that got stored when invoking the operator (i.e. the toolshelf).
This change doesn't have any real user-visible effects, other than making it possible for
this fix to actually work without breaking that use case.
This commit fixes several issues:
* island_store->items_to_islands_num was reset each time we added a new island, this is stupid! Harmless too, though, afaikt.
* partial verts bvhtree (with several islands) was hugely over-allocated...
* we would 'leak' in neighbor islands when geometry itself was contiguous.
* best_nor_dot was used incorrectly, leading to smaller weights for better matching normal!
All those fixes are related to T44522 (through personal communications with reporter).
Alternative to T32894, simple test which creates new data and compares with RNA defaults.
Can be used to keep the values in sync without having to maintain a large set of defines.
