This prevents twisted quads from self-intersecting.
This change makes the duplicate surface match the first vertex in the face,
so the diagonal indices match in the face copy.
Previous fix made another issue even more visible, leading to +1 particle on first vert
and none on last one. This commit should fix both original and new issues.
The patch contains an implementation of the wide lines and the line stipple that is necessary for OpenGL upgrade.
For the implementation I have chosen the geometry shader because it required minimum changes for the wrapper calls and such implementation is the best for the "basic shader" architecture.
There are few shortcomings that can be corrected in future. They all are related to the fact that the lines in one strip are not connected with each other. So the stipple pattern is not continuous on the common vertex of two lines. There is also no continuity of form (each line is an independent rectangular).
But the advantage is that even outdated glBegin, glVertex work! Though with the above restrictions.
Continuity of form and stipple can be implemented with additional attributes, and it will require more changes in calls.
At the moment, the patch replaces calls for some "gestures". It works satisfactorily for "cross" or "rectangular" and not so good for "lasso" and "circle" due to the above-mentioned shortcomings.
Don't forget to set USE_GLSL to true for testing.

This patch depends on D1747, which upgrades the Recast version. It exposes the new Recast partitioning methods in the navmesh generation.

The version of Recast that Blender ships with is from 2009. This patch updates the Recast version to the latest version, 1.5.0. The Detour version remains untouched.

The addressed issue is a regression from Blender 2.75, after the internal
switch from double to single precision floating-point numbers in the
Freestyle code base. Face normal calculations require the higher
precision during the computations, even though the results can be stored
as single precision numbers.
Support for driver variables that don't resolve to numbers, eg:
objects, bones, curves... etc.
Without this, Python expressions to access this data needed to use an absolute path from `bpy.data`,
however this is inconvenient, breaks easily (based on naming) and wouldn't set the dependencies correctly.
This fixes reported issue, but there could be more of those hidden in Freestyle code,
it did not handle user refcount at all (and the fact it by-passes BKE in some places
for efficiency does not help here).
Note that this should be relatively harmless, since freestyle uses own Main during
render, so everything is cleaned up in the end in any case... But better try to
handle IDs correctly here too. :)
Note that we may want to review that some day, we have quite a bit of ID types here that are
'blend file' view only, might be worth splitting the check based on this.
That might consider a bit more objects to be considered deform modified,
but it covers common case of using taper object without require of doing
recursive checks.
In worst case it'll be just some extra synchronization time, no render
time difference will happen for false-positive because of extra checks
happening in Cycles.
The improved Hosek / Wilkie model was added during my GSoC 2013 and the default since then.
The older model was kinda kept for compatibility, but after more than 2 years it's time to remove it.
The Hosek / Wilkie model is more realistic anyway, and people who really want a day / night transition can mix the Sky Shader with another one (e.g. color) and fade between the two.
