The popover for displaying gizmos now has options for
empty, light & camera gizmos.
Transform toggles are now checkboxes, which has the advantage that it's
more obvious they can be mixed however changing from one to another now
uses 3x clicks instead of a single click-drag action.
We might need a faster way to switch between transform types.
Based on feedback from animators, this is useful to keep as a view
option (as in 2.7x).
Now the transform gizmos can be enabled from the popover,
the tools still work for location/scale/rotation.
The transform tool has been removed.
See T63518
Do not gray out shading items if the xray alpha value is 1.
They are rendered correctly in viewport so there is no reason to mark
them as disabled in the shading menu.
A version for menu's is going to be added next and we already have
UILayout.prop_menu_enum.
This name indicates the popover is added behavior instead of a
different kind of widget.
Unlike most transform operators that use an orientation and values,
Mirror uses the constraint axes to define which axes are mirrored.
Now constraint axes are shown in this case.
Other changes:
- Use 'EXEC_DEFAULT' for mirror menu items.
- Show mirror on local axis when not in edit-mode since this is useful
in object mode too.
- Remove mirror vertex groups since this is in the vertex group menu and
this menu isn't currently used for general symmetry operators which
are currently in other menus.
Prepare for exposing tool registration to the Python API.
- Generated tools can use their own prefix so naming collisions
won't happen between hard coded & generated tools.
- Add-on authors can use the add-on name as a prefix.
Currently the names match, renaming will happen next.
staticmethod shouldn't be used unless it's necessary,
in that case a comment should be included especially when
subclassing non-staticmethods from RNA.
Now when the text argument is omitted, use the default name
matching how regular properties work.
Avoids passing in the same name which RNA has,
matches UILayout.prop behavior.
Also use keyword only for optional arguments.
In keeping with convention to match code & UI naming.
- No user visible changes.
- Include 'menu' in the name since context is an overloaded term.
- While a few of these are panels, from a user perspective they are
still context menus.
