WIP: Reorganize parameters in old draw mode

The list of parameters was too long and it's better pass a struct.

This is the first step to use the new shaders with the same functions of Draw manager. This is used in interpolations, filling and primitives while the operator is running.

Sparser edge drawing for grooms to reduce visual clutter.

Shape binding for groom curves to the scalp mesh surface using face groups.

Face groups are used for now to define the origin of a groom bundle. This
is probably going to be replaced at some point with a dedicated surface
graph/mesh, but is much easier to implement and gives sufficient functionality.

When a face map is selected as the basis of a hair bundle it will update
the curve shape automatically. In the future this should perhaps be an
optional step (user operator) because it destructively changes existing
shapes.

New Weight Invert operator

This operator invert the weights of the strokes.

Make weight paint vertices smaller

UI: Change Simplify Name

fix T52831 removed enforcement of matrix decomposition when animations are exported

Fix T53017: Cycles not detecting AMD GPU when there is an NVidia GPU too.

Best guess is that cuInit() somehow interferes with the AMD graphics driver
on Windows, and switching the initialization order to do OpenCL first seems
to solve the issue.

Enable Draw on Back for fill Brushes

Merge branch 'blender2.8' into greasepencil-object

Scale stroke thickness when scale stroke

Now when scale a stroke, the thickness is scale to.

The operator to scale only thickness is available too using Shift+S

Merge branch 'blender2.8' into greasepencil-object

Apply falloff to Scale

Apply falloff to rotation

Apply falloff to transform

WIP: Save falloff factor for transformations

This data must be used by transformation to determine the effect of the change.

Also enabled the falloff option for edit mode.

Math Lib: add divide_floor_i

Integer division that floors on negative output (like Python's).

BMesh: move bridge tools stepping logic into macro

Also use floor division since regular division was giving a bias
on negative error values.

BLI_utildefines_iter: Use for iteration helpers

Fix T53143: Knife Crash after Grid Fill

BM_ELEM_INTERNAL_TAG flag wasn't ensured to be cleared.
