Fix unreported error: Algorithm for extracting the Bounding Sphere from an Orthographic frustum was incorrect.

There was double transformation.

Fix two more 'infinite recursions' cases in RNA pose.

Merge branch 'master' into blender2.8

BKE_context: macro to access ID's while looping

Merge branch 'master' into blender2.8

Depsgraph: Pull indirect relations via driver targets

Switch 'make static override' of group to making all objects local overrides.

Note: tried with a complex production file characters, this is currently
totally non-functionnal (crashing even in a infinite recursion loop),
IDProps and override need some love :(

Fix warning: Passed ID pointer where screen pointer was expected

Fix rBb31ebd8c5c55: the asymmetric furstrum algorithm was still incorrect.

Although somewhat less micro efficient, I decided to separate the `viewinv` matrix to calculate the world position separately.
This makes it easier to understand the code.

Merge branch 'blender2.8' into topbar

Cleanup: move some screen utility functions, from topbar branch.

Cleanup: split off area reading/writing functions, from topbar branch.

Fix build errors after recent depsgraph changes.

Merge branch 'blender2.8' into blender2.8-workbench

Workbench: Added Object Color to collection_properties

Fix stubs

Fix T54609: Erros in precise BBox extraction algorithm

Depsgraph: Tag scene after changing cursor location

While 3d cursor is mainly an UI thing and isn't needed for scene evaluation,
it is stored in scene DNA. This means, operator is inform depsgraph that data
has changed, so all copies of that scene can copy new values.

Fixes lack of visual feedback when changing cursor location in viewport
with copy-on-write enabled.

Cleanup Collada: Renamed Enum entries for consistency

Minor change: indentation of BC_ANIMATION_TYPE_FROM_NAME was wrong

Cleanup Collada: Removed no longer needed method
