Fix T52136: Blender segfault (stack overflow most certainly) when converting to mesh.

Stupid mistake in own recent refactor.

UI/floats: Reduce our UI_PRECISION_FLOAT_MAX by one to avoid most rounding issues.

The way we use it, UI_PRECISION_FLOAT_MAX is actually + 1 to get total
number of digits, and float only has 7 meaningful digits, so that define
shall be at 6.

WIP: More work on modifiers

Reorganize the system to create new strokes in array modifier

Set face-map to active when selecting

It was annoying have to use select operator to know which facemap
applies to the active face. This behavior follows materials.

Fix a few harmless maybe uninitialized warnings with GCC 5.4.

GCC seems to detect uninitialized into function calls now, but then isn't
always smart enough to see that it is actually initialized. Disabling this
warning entirely seems a bit too much, so initialize a bit more now.

Fix T46560: 2D paint smear and soften brushes not working with alpha.

Interpolate rather than do alpha over mix, matching projection paint.

Eevee: SSR: Add firefly filter and refine noise reduction.

Push to 9 resolve sample.
Add an normalization as an option since it gives harsh limits.

Eevee: Codestyle.

Eevee: SSR: Do the SSR pass only for probes if there is no valid double buffer.

This prevent black reflection when initializing SSR.

Fix T52135: Cycles should not keep generated/packed images in memory after render.

Fix potential memory leak in Cycles loading of packed/generated images.

initial tracer particle support

fix for particle float type define

PFLOAT name collided with PFLOAT from windows header

Eevee: SSR: Add mipmap filtering and bias to reduce noise.

Also fix the roughness factors.

Depsgraph: Fix crash when updating materials with copy on write enabled

The code was freeing GPU materials from non-main thread.

Fix T51925: Eevee: Animated Eevee values slowdown

Move material update from RNA callback to dependency graph.

Basic support for rotation/scale in array modifier

More work on modifiers

Complete rework, now the modifier data is saved in a cache and is not recalculated for each redrawing. The previous version had the problem the array strokes suffered of effect acumulation.

The array modifier is pending to add the rotation and scale parameters. Now only appear in UI panel but don't work.

Eevee: Fix glossy node roughness.

Manipulator: add access to manipulator's group
