Inline function BKE_mesh_boundbox_calc inside BKE_mesh_texspace_calc to avoid confusion.

Keymaps: keep Select Box as default tool.

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.

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.

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

Cleanup: remove unused code & add comments
