Fix unpredictable trackball rotation

D2729 by @IgorNull

Currently, trackball rotation sequentially applies rotation across x axis and y axis,
which produces a strange/unusable result on diagonal pointer motion.

This change fixes the problem by using a single axis which is orthogonal
and proportional to mouse delta - matching view-port trackball.

Workaround T51934: Array's > SHRT_MAX aren't supported

Eevee: Fix broken default coordinate (reported via IRC by Dalai Felinto).

No need to free all the shaders when appending or reloading libraries

To recompile all the shaders is expensive. And something to be avoided at all costs.

It was needed before because for every new lamp in the file we needed to
recompile the shaders. Now this is no longer required since we are using
UBOs for the sahders.

Eevee: No need to free all the gpu materials when world changes.

We have a world probe that is used to prevent exactly that.

Fix hair shading after Eevee shader refactor

Eevee: Fix world probe with world without nodetree.

Eevee: Remove Geometry shader usage for background.

This fix the behaviour of the light path node that separates the probes background from the viewport background.

Eevee: Fix T51922: Avoid division by 0.

Problem was caused by a division by 0 when rendering the probes. This patch make the visibility equal to 1.0 in this case.

Eevee: Prepare support for future Anisotropic shading.

material Glsl: Fix tangent with new orco.

Remove dupli-group support for non-empty objects

Behavior for mixing object-data & dupli data was confusing,
exporters and render engines often got it wrong.

Fix warnings in draw_cache_impl files

Fix T51890: Turning off viewport display for array modifier is blocking dupliface in final render

DupliVert/Face were not using render DM at render time.

Fix T51821: Viewport not updating when switching worlds

Fix error getting the tangent layer name

Fix world not updating when changing node links

When changing node links for the world material, a redraw of the
viewport was not being triggered.
