GPUMaterial: Group all colorband texture together

This lower the use of texture samplers slots and let users use more real
textures in their shaders.

This patch also make the ramp texture 16 bit floating point. Meaning you
can now use value greater than one in your color ramps.

With the limit of 128 colorband per shader (a color band being either a
color ramp, a wavelength node or a curve node (and maybe wavelength node in
the future)).

Only drawback with the current implementation is that it does not remove
colorband from pruned GPUNodes but it shouldn't really matter in practice.

This should fix T56010

UI: Fix nodelink not touching inputs when noodle_curving is 0

GP: Set instance maximum value to something more logic

build_environment: update freetype to 2.9.1

Python: Add support for @ infix operator matrix multiplication

Fix build error due to missing file from commit 98c304e865f8.

Proper contents still needs to be added, this just makes things build.

Fix unreported assert error when change instance modifier

Doing very fast change in the number of instances soemtimes get an error of duplicate ghash entry.

Gizmo: add option to catch all mouse clicks

This was previously default behavior, now it's default.

Gizmo: support for 2D selection checks for 3D gizmos

This means 3D manipulators can use their own logic
for checking if the cursor intersects.

libs: boost 1.68

Cleanup: style

Gizmo: 2d select now takes region coords

Was taking an event, when only the region coords are needed.

build_environment: move llvm/clang to ninja on windows.

Quiet warnings in bmesh_bevel.c.

Merge branch 'master' into blender2.8

update llvm + clang to 6.0.1 and add openmp for macOS

Eevee: Fix assert with subsurface bsdf

Eevee: Principled BSDF: Add support for the sheen parameter

This is a rough (but fast) approximation that still match cycles reference
in common case.

In practice, it's just adding more of the diffuse light computed for the
diffuse contribution.

Fix T56279: Grease Pencil transformations show a help line with wrong origin

As grease pencil use multiedit frames instead of multiobject edit, this fix solves the issue.

In the future maybe will need modifications if we add multiobject support, but we need a solution now.
