Fix gizmos not using same tweak threshold as other places.

The low hardcoded threshold made clicking on the navigation gizmo difficult
on tablets.

UI: expand tooltips for left/right click select.

Added temporary contour bypass for smooth contour modifier build.

Fix inverted texture paint overlay display icons.

Defaults: set "release confirms", for transform tweak with single click and drag.

The old behavior with two clicks evolved out of a gesture system, and it can
have some advantages if you want to press more keys to constrain for example. But
this seems a better default.

Merge branch 'master' into blender2.8

CMake: Remove Cycles specific OpenSubdiv options

Just use one flag which enables OpenSubdiv globally for all the
areas of Blender.

Rename Bled Layers to Layers Blending

Fix texture space not updating in edit mode.

transform_snap_object: fix ray_start_correction in snap to edit_mesh.

Fix T56167: Crash when extruding + snap to face.

This is a local fix.
The problem with duplicate looptris still remains.
That is, it can still be released in one place but not upgraded in the other.

(note: setting the looptris to NULL in the evaluated mesh and assert whether it is still NULL when the mesh is freed could indicate where those cases are).

Fix T57985: Out of the edit mode, the texture space is affected by the modifiers of a mesh.

Go for the simple solution for now (disable auto-texspace in evaluated mesh).
Proper fix would be part of known TODO redesign of bbox handling.

Solution suggested by @sergey, thanks!

UI: collapse redo panel by default

For some operators this fills a lot of vertical space,
users can expand it if they need.

Also remove workaround for T56752 (now fixed).

Correct last commit

Initial display was fixed, broke refreshing.

UI: fix glitch showing redo panel

There were still cases it would show for the first time w/o content.

Fix crash accessing mesh.point_normals default

This memory needs to be static,
in this case the argument isn't needed so remove it.

Keymap: use 'W' key for select toolbar shortcut
