Fix: Make Single User wasn't supported for GP Objects

Fix: Doing a Scene "full-copy" wouldn't relink the gp_object

Add missing header

Revert "Fix T52871: `BLI_polyfill_beautify_quad_rotate_calc_ex` was mistakenly considering the state as degenerated"

This reverts commit a8f11f5422afa01608817755eea310e987f896be.

Result is no longer symmetrical, will investigate a different fix.

Fix T52871: beauty fill error

Only lock tri's facing different directions.
Needed because scanfill creates zero area faces.

Fix T52901: New Depsgraph - Driver using "self" needs reloading file to work

Fix: When transforming GP strokes in "Local" mode, the strokes would get obscured
by the transform constraint lines

Ported over e7395c75d504af2c2f720f43ea27b93e04a378e4 from the
greasepencil-object branch. I should've fixed this ages ago, but
couldn't figure out why at the time.

deps libs: fix xiph library support on sndfile on macOS

Re-enable Amber asset engine.

Update Amber to take into account new View level.

Also get rid of hack mixing repo and asset uuid into same UUID, now we
do have a real repo UUID in API.

Everything seems to be be back on par with pre-View changes status.

Fix various mistakes and forgotten bits in previous 'Views' adding commit.

Core API code shall now be mostly functional again.

Eevee: Implement Temporal Anti Aliasing / Super Sampling

This adds TAA to eevee. The only thing important to note is that we need to keep the unjittered depth buffer so that the other engines are composited correctly.

DRW : Add new view_update mechanism.

This makes updates for the viewport cleaner and also add the possibility to add a new callback called when the scene is updated.

Eevee: Fix SSR in orthographic view.

The problem was that orthographic views can have hit position that are negative. Thus we cannot encode the hit in the sign of the Z component.

The workaround is to store the hit position in screenspace. But since we are using floating point render target, we are loosing quite a bit of precision.
TODO: use RGBA16 instead of RGBA16F. But that means encoding the pdf value somehow.

DRW : Add AA to non meshes objects.

You can change the amount of samples in the user preferences. You do not need to restart blender to see the effect in the new viewport.

This adds another Multisample Framebuffer and textures (so even more memory required).

It works by blitting the default_fb to the multisample_fb each time the renderer need to render one or more "wire" pass.
It it then blit back to the default_fb so that the rest of pipeline is working as expected.

We COULD lower the GPU memory / bandwidth usage to render everything to the same multisample fbo and change the logic depending on if MSAA is enabled or not, but I think it's a bit too much work for now.

GPUTexture : Fix Bind/Unbind function so it works with multisample textures.

GPUFramebuffer: Fix Blit function so that it works with multisample textures.

Fix compilation error after recent merge

Merge branch 'master' into blender2.8
