was an old issue since the first version.

UI / Modifiers:
* VERTEX_WEIGHT modifiers had quite a messy UI, improved the grouping of options a bit, so it is easier to scan through.
* Do not use abbreviations like "Rem" or "Dist" in the UI...

* Also small change for BEVEL modifier UI for more efficient space usage.

UI / Modifiers:
* Skin modifier also wasted quite some space, use dual column layout now.

* Properties, which depend on an enum should be hidden, not greyed out.

Fix for node search operator, this was not taking into account possible NodeItemCustom in the categories yet. Such custom items as just ignored for now.

Cycles: invert mist pass so that 0 is nearby and 1 is far away. This is the
opposite of Blender Internal but it makes more sense I think.

Fix compilation of cycles for MinGW-w64 after recent commits. MinGW-w64 has conflicting redefinitions of the SSE functions in windows.h, so we will be using this header instead, since we can't always avoid including it instead of the sse headers.

add editmode wire color,
also changed lattice to use this, it used a hard-coded green color which was hard to see over the default background.

Removed the 'custom node group' example from the pynodes template script. This does not work properly due to the fact that node groups don't have a single registerable base class any more. The reason for
that is that RNA does not support multiple inheritance so the actual node group subtypes (ShaderNodeGroup, CompositorNodeGroup, TextureNodeGroup) can not be derived from both the
ShaderNode/CompositorNode/TextureNode base types as well as a common NodeGroup type ... It is possible however to define node group types entirely in python which avoids the limitations of the RNA system
and is much more flexible, example for this will follow later.

Removed the unused draw_add_menu function from pynodes template. This was previously used to extend the node Add menu, now the node categories system is used instead.

Fix #35677, #35525: cycles viewport not updating properly in some situations.

Revision 56883 broke a mechanism where cycles tags itself to be updated later
while it is busy.

Bugfix [#35686] Grease pencil to curve conversion causes NAN weights on vertices

When you convert a grease pencil stroke to a polygon curve and look at the
vertices, the first and last vertex have weight = 0, but all others have a -NaN
value. This was caused by division by zero issues when minmax_weights[0] ==
minmax_weights[1].
