Fix compiling on MSVC - M_PI undefined

Action Editor: Initial support for a Properties Region

This commit adds some of the initial support for a properties region in the
Action Editor. There are currently no panels to display, as there is still
a lot of work required to port over the required internal architecture to
support the panels seen in the Graph Editor.

D1886: GPencil - Add smooth iterations parameter to get better quality

After some test, a new iteration parameter has been added in order to
apply repetitive smoothing to the stroke. By default 1 iteration is applied,
but can used any number between 1 and 3.

The repetition uses different levels of intensity from 100% of the defined smooth
factor for the first loop, 50% for the second and 25% for the third. We use in each
loop a smaller value in order to avoid deform too much the stroke.

Fix for D1705: Update to fix the bug with extra triangles that produces glitches in some situations

GPencil Fills: Small reshuffle of UI buttons

Now, stroke-related things (thickness, volumetric, points) and fill-related things
(HQ fill) are in the relevant columns, instead of having some in each column.

Code Cleanup: Just a bit more tidying up comments/whitespace/etc.

There is still some instability in how the triangulations are happening,
where the triangle count of the resulting triangulation fluctuates resulting
in weird artifacts sometimes.

To reproduce, try drawing some U-shapes, and keep reloading the file.

Fix for potential bug with new GP Fill

While trying to track down why I still keep getting some random "extra" triangles
showing up when reloading files with fills, I noticed that there's an index mismatch
here that may cause problems in some rare cases:

There are "gps->totpoints" items in tmp_triangles, but there should only be
"gps->tot_triangles" triangles in the gps->triangles array. If for whatever reason
some of the triangles in tmp_triangles are invalid, this could have meant that
while a tmp_triangles candidate was skipped, a corresponding slot for a valid
triangle also got skipped.

Code Cleanups: A bunch of tweaks to tidy up things from the GPencil Fill patch

D1705: Fix Grease Pencil Fill for Concave Shapes

Improve filling for concave shapes using a triangulation of the stroke.
The triangulation information is saved in an internal cache and only is
recalculated if the stroke changes.

The triangulation is not saved in .blend file.

Differential Revision: https://developer.blender.org/D1705

Fix T48373: Crash when using dynamic paint with brush material.

`dynamicPaint_doMaterialTex` was called from inside an omp parallel section with brush->dm
itself, and not the local dm copy. Generating looptri data is not thread safe at all...

Cycles: Cleanup: Swap order of the RNG-state-initializing for-loops

Swap the for-loops in the RenderBuffer reset code to follow the convention
of looping over y in the outer loop.
The improved cache performance won't really be noticable here, but it's nicer
if it follows the usual style.

Clamp dot-product to avoid precision error

Would only happen in degenerate cases.

Cleanup: whicespace

Cleanup: Remove unneded (void) line, we don't have ifdefs here anymore.

Correct render-border line width

Correct error in wrapped array-span-iteration

Fix T48368: Cycles mix RGB constant folding bug after recent refactor.

Curve Fitting: better fallback when least-square solution fails

Take curvature into account when calculating handle length.

Gives significantly better results for curve dissolve and 10-20% more efficient freehand drawing.

Fix error copying cubic data

Fix T48362: Spin tool broken after recent commit.

Typo in rBrBa48d74079, spin tool was now using the wrong view axis.
