Fix #36962, "Render emitter" option for hair is ignored in Cycles. Hair particles use the hide_tris boolean to disable rendering of the emitter, but this was still ANDed with the "experimental" flag.
Hair is not experimental any longer, so this has to be removed.

rename overlap to holes for isect_point_poly_v2

avoid divide by zero with grid fill (when there is no selection)

more corrections to valgrind hinting.

use valgrind hints for memarena for better debugging info when using valgrind.
also quiet a false positive in BLI_mempool_free().

pressing enter over a file-text button is ignored (so enter in the file selector works again).

Fix cycles hair render UI panel showing for particles that are not hair,
patch by Greg Zaal.

Remove prints from own r60549, sorry for the noise.

code cleanup: warnings and minor edits.

fix for lasso failing/glitches on overlapping lines, replace scanfill with 2d pixel filling for drawing and selection.

Attempt to fix #36935: disable SSE optimizations on 32 bit windows too. Something
strange is going on here, but I don't think it can be fixed before the release,
if it is worth at all spending time on this.

Fix obvious bug in particle code (copying normal into nor when in if(ornor) block...), though probably harmless in current code...

Fix #36930: dynamic topology sculpting with masks gave bad results:

* The mask was not subdivided properly on splitting edges, which gave interesting
but definitely wrong fractal-like borders around masks.

* Edge splitting was only done where the mask was < 50%, with the reasoning that
you can't do a 50% topology update. But this gives an ugly border in the mesh.
The mask should already make the brush move the vertices only 50%, which means
that topology updates will also happen less frequent, that should be enough.

Fix #36948: blender internal viewport render crashes holding shift+Z pressed
to quickly toggle it on/off.

Problem is accessing freed data, now the job is ended immediately. Fix based
on patch from Sergey and investigation from Bastien.

Code cleanup: remove unused function

Fix related to [#36926] 'scale' Node doesn't work properly.

Scene/Render "spaces" are actually absolute values, they do not use the input X/Y scale factors, hide them in this case.

Thanks to Lukas for review and improvement!

fix for lasso selection (in non-zbuf mode) when the line intersected its self.
isect_point_poly_v2() - add argument to check overlapping areas.

Changing dither value will now invalidate cached display buffer

Fix #36939, Objects with nodes appear in gray in viewport, using Solid shade, and the Blender Engine (or Game Engine).
The "active ID node" concept has become slightly more complex with pynodes. To find the active material or other ID links in a node tree recursively requires a hash key based on the "parent" tree of the
current node group. To avoid returning NULL in case this key is not yet initialized (i.e. ID node has not been activated yet), just accept 0 key as well for the base node tree.

fix [#36947] "Edge Slide" bugs when "Even" is on

was doing a linear interpolation between points on either side instead of interpolating along the edges.
