GPencil: Create Linear gradient fill colors in SVG conversion

There are several limitations in this conversion because SVG support multiple color, but GP only 2. For GP only the extreme colors (first and last) are used.

The mix factor is always set to 0.5.

The angle of the gradient is calculated using the direction of the line defined in Linear gradient.

New boolean math node with And, Or and Not operation

fix boolean c++/llvm conversion

Nodes: Support for socket shapes other than circle

Previously there was already "draw_shape" property,
but it was doing nothing. This commit renames the
property to "display_shape". Furthermore, different
shapes like SQUARE and DIAMOND are supported now.

Currently, the shapes are drawn using the shader that also
draws keyframes. In the future we might want to separate
this.

The new shapes are not used anywhere yet, but they can
be used by addon developers and will probably be useful
when we want to support different kinds node systems later.
For example, different shapes can be used to distinguish
between data and control flow.

OpenVDB: Made all modifier parameters animatable.

Cleanup: remove edit-mode check in vertex coordinate access

This makes the function more predictable since other object
types don't access edit-mode data.

Cleanup: typo in last commit

Updated VertexSnap patch against recent 2.8

Fix alembic code merge issues.

Cleanup: vertex coordinate access, naming & minor changes

This also splits vertex access and allocation so it's possible
to copy coordinates into an existing array without allocating it.

Don't create a DirectX swap-chain

We only render offscreen anyway. There's no point in creating a
swap-chain. This simplifies things quite a bit.

Cleanup: use doxy groups

DirectX: Create an own render-target, don't use swapchain for blitting

Cleanup: clang-format

Remove GHOST API functions for OpenGL offscreen blitting

These were previously used to blit from a offscreen (non-OpenGL)
context, into an onscreen one. We do this differently, and only within
GHOST_XrGraphicsBinding now, so this can be removed.

Shading: Add Volume Info node.

The Volume Info node provides the Color, Desnity, Flame, and Temperature
of smoke domains.

Shading: Add White Noise node.

The White Noise node hashes the input and returns a random number in the
range [0, 1]. The input can be a 1D, 2D, 3D, or a 4D vector.

Refactor OpenGL/DirectX resource sharing for multiple shared resources

Rather than max. one shared resource per DirectX context, code can now
request a handle for a shared resource and ask the DirectX context to do
operations on that.
