Merge branch 'blender2.8' into greasepencil-object

Merge branch 'master' into soc-2016-pbvh-painting

fluid particles UI update

cleanup for adaptive time stepping

especially the timestep was too big and resulted in adaptive steps when adaptive stepping was actually disabled.

Cleanup: unused function

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

GP Palette Slots - Initial DNA structures

Start of support for GP "Palette Slots". These act like "Material Slots"
in that they allow a single GP datablock to refer to multiple Palette
datablocks, making it easier for the user to manage the set of available
palettes.

Code Cleanup - Clarifying names, comments, and shuffling fields for clarity

Cleanup: move accumulation structs out of sculpt-session

These were over-allocated to the size of all pbvh nodes.
Now only allocate as-needed,
using the total number of nodes under the brush.

Avoid redundant vert->loop->vert topology lookup

This is only needed for vertex colors, vertices store their own weights,
so this is redundant.

Cleanup: split vert/weight paint into separate members

- Remove unused previous wpaint/vpaint struct members.
- Avoid allocating arrays when they aren't used.

Code Cleanup - Move all old/deprecated bGPDpalette stuff together to be easier to remove/disable in future

Code Cleanup

Resolve bug w/ non-airbrush weight-paint blending

Instead of clamping the max-weight (which locked the value at 1.0),
Store the initial weight and maximum strength used for painting.
Repaint only with a higher strength, using the initial weight.

Build fixes after merge

Merge branch 'master' into soc-2016-pbvh-painting

Code Cleanup: Move 2D Monkey code to its own file in editors/gpencil

Fix: The code to reset GP Objects to Object Mode on load wasn't working

Use BLI_math rounding function, replace sqrtl w/ sqrtf
