This support layout.separator_spacer() to be used by headers as a way to
dynamically separate the ui buttons.
Right now no UI file is changed, though we can use this right away in the
timeline, and shortly after in the viewport header (moving settings from
the topbar to it).
Original design by William Reynish.

This commit implements a new behaviour for the "Add Driver" functionality
(invoked from the RMB menu on a property, or by pressing Ctrl-D).
Instead of spawning a context menu asking you to pick the way
you want to create a driver, it will now just create a driver on the
property under the mouse and then show the "Edit Drivers" popover so
that you can immediately start editing the properties of this driver.
This way, the whole process is more visual and feels less blocking /
constrained, with less upfront decisions needed immediately.
Notes:
* The new behaviour is equivalent to choosing the "Manually Create (Single)"
and then doing a "Edit Driver" on the property
* Renamed the old "ANIM_OT_driver_button_add" operator to
"ANIM_OT_driver_button_add_menu". It will probably go away
in the near future, but it's better to keep it around for a
while longer still until the new workflow settles down.
This mimics the 'spreadsheet' behavior. Columns and/or rows can have
equal sizes, or adapt to their content - but always in a grid way (i.e.
all items in a same column will always have same available width, and
all items in a same row will always have same available height).
Also, you can fill (order) the grid in a row- or column-major way.
Not used anywhere for now.

Notes:
* Really need to address RNA setters case, end up adding way too much
G.main here these days... :/
* Added Main pointer into bAnimContext, helps a lot in anim code ;)
Test this since the popup feels disruptive/flashing when its too large
when set smaller it looks closer to a menu w/ key-accelerators which is
the intention in this case.
It's also more likely the active tool can be placed under the cursor.
In the Python API, any panel becomes a subpanel by setting bl_parent_id
to the name of the parent panel. These subpanels can contain advanced or
less commonly used settings.
Since the viewport header now supports transparency, text on pulldowns
can be hard to read if their color matches the viewport content.
Background is drawn using the 'inner' theme color, that was unused until now.
This currently shows panels that were in the 2.79 3D view toolbar
which are now popovers.
In some cases it's useful for these to stay open.
This commit adds a space type to do this.
Note this is currently empty in object mode.
