The CANCELLED return value from an operator is intended for
signaling that the operator aborted execution without changing
anything, and an Undo stack entry should not be created.
When a Python operator crashes, it is not safe to assume that
it did nothing, so it should interpret it as FINISHED instead.
Otherwise, the undo system behavior after an operator failure
feels broken.

Currently, we use the crosshair cursor in Sculpt mode, but not in the other paint modes.
- Sculpt Mode: This crosshair cursor is too weighty.
- Texture, Weight, Vertex Paint: Using the arrow cursor for painting is not right.
This commit makes the following changes:
- Use the new special paint crosshair instead
- Use this cursor in all paint modes, not just Sculpt

There was a mix of old and new constants. Now have one list of WM_CURSOR_*
cursor types, using GHOST standard cursors when available and otherwise falling
back to our custom cursors.

For operators with dynamic tooltips the tooltip calculation is
deferred until the moment it is actually shown for performance
reasons, with the tooltip field left blank for the time being.
Enum menu code shouldn't jump in and assign a tooltip either.
The menu button itself can't show a dynamic tooltip because it
does not actually call the operator, and has no reference to it.
As a side change, allow returning None from the python callback
as the most natural way to fall back to the default tooltip.
Blender UI Layout API allows supplying parameters to operators via
button definitions. If an operator behavior strongly depends on its
parameters, it may be difficult to write a tooltip that covers all
of its operation modes. Thus it is useful to provide a way for the
operator to produce different descriptions based on the input info.

This is useful when popovers are launched from operators
instead of as button popover types.
Where the connection between the button and the popover is useful to keep.
This reverts commit a412f49e75 and 873c756e5d. The change was only
supposed to affect grease pencil, but also changed the cursor for sculpt mode,
where it's not clearly visible. Since this has not been quickly resolved I'm
reverting the commit.
Ref D5036.
This new cursor is used instead of the ARROW because it was too disruptive while you are drawing.
The change affects all paint modes that are used Brushes.
See D5036 for details.

This feature is intended only for testing,
to automate simulating user input.
- Enabled by '--enable-event-simulate'.
- Disables handling all real input events.
- Access by calling `Window.event_simulate(..)`
- Disabling `bpy.app.use_event_simulate`
to allow handling real events (can only disable).
Currently only mouse & keyboard events work well,
NDOF, IME... etc could be added as needed.
See D4286 for example usage.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
