This commit is meant to improve the response of the ESC key for stopping Freestyle rendering
throughout the rendering process. The rendering with Freestyle consists of several steps
including: (1) mesh data loading, (2) winged edge construction, (3) silhouette edge detection,
(4) view map construction, and (5) stroke drawing. All these steps have been extended to
frequently check if the ESC key is pressed, so that users can abort time-consuming rendering
at any point of time.
Real fix would be to find a point which is definitely now on loop
to be collapsed, but that's for a bit later. This commit should
remove possible stoppers.
This implements simple function which collapses internal loops
caused by self-intersections into a singularity.
This loops can't be removed because rasterizer expects points
of feather be aligned with points from spline itself.
When OpenMP is enabled, memory allocation needs to be protected.
Fixes bug [#32111] Memory management regression from svn_46520

Several users requested the recovery as the removal of the two parameters was considered over-simplification for advanced users.
As in the Python Scripting mode, the two parameters are in the "advanced edge detection options" section and disabled by default.
Also the lower limit of Kr derivative epsilon was changed from 0 to -1000 so as to permit a negative value.
This auto/heat vgroup creation seems to be fuzzy/unstable (each run gives a slightly different result). I have not the competences (nor time) to investigate that laplacian stuff, so for now just adding an option when parenting to an armature with envelope/heat, to mirror weights along the X axis (as it is done by default when doing it from the Weight Paint mode).
This deadlock was caused by lock of threads using LOCK_DRAW_IMAGE
mutex and lock used in render result acquire functions.
So if image draw would lock LOCK_DRAW_IMAGE before compositor
operation released render result it'll lead into a deadlock.
Refactored code a bit to make naming a bit more clear and added a
function to create mesh from given display list rather than from
object's displist.
Tested using plain curves (which doesn't imply using derived meshes)
and curves with constructive modifiers (which are using derived meshed).
notes:
- uncomment #define USE_RASKTER in BKE_mask.h to use the previous mask rasterizer.
- slightly slower for regular masks but significantly faster for feather.
- main benefit is that it threads well so works nice for tile compositor.
- feather is lower quality, can use some improvements here.
- feather can also use some interpolation enhancements, will do later.
This commit adds "shift" and numtype to both Bevel and Inset mesh operators.
It also gets rid of the magicnumber used in NumInput to str operation (currently, 20 chars per element, now defined as NUM_STR_REP_LEN in ED_numinput.h).
