Revert "Compositor: Added Weighted Standard Curve evaluation"

This reverts commit b8c9df6f21587014cb6f11aa5bed6f9c1044e6ee. The code is not
correct with regards to color management, and its purpose was not documented.

Cycles: Fixes for OSL with texture caching: Textures are now right side up again and textures read from the cache are assumed to be linear.

GP: Check weight data before using it

Fix T56920: Crash: Renaming bone through outliner

Cleanup: Silence strict compiler warning

Was happening when using OSD for modifiers.

OpenSubdiv: Cleanup, the TODO was actually solved

Clip editor: Fix usage of template_marker

Needs an update to the new Python API.

Reported by Sebastian in IRC, thanks!

GP: Adjust topbar layer selector to new fixed width

OpenSubdiv: Cleanup

Fix access past array boundaries

Need to resize `have_functions` arrays when adding more functions.
Not sure there is more reliable way which will prevent accidents
like this.

Was caused by c47be43674f5.

Cycles: Set proper defaults for texture caching.

Gizmo: initial snap support for move

This allows the gizmo to snap to 3D view elements,
Although currently this isn't usable gizmo's that use operator redo.

Gizmo: support for cancelling move3d modal changes

Gizmo: add invoke_prepare callback

Allows gizmo groups to set values based on the gizmo about to be invoked.

Spin Tool: match dial orientation to active gizmo

Fix misleading field naming.

This is not any kind of length, it is the number of true values.

Spin Tool: option (disabled) for gizmos to follow selection

Disable since this causes multiple axis to overlap too often.
It's also glitchy since we don't have a good way to detect
changes to selection.

Correct error in last commit

Didn't account for non-identity orientation.

Spin Tool: correct the initial redo dial rotation

Merge branch 'master' into blender2.8
