Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
- Key-map items properties now override tool-options
so modifier keys can have different behavior to the default action.
- Box & circle select now have `wait_for_input` properties
instead of detecting this based on selection options being set or not.
This relied on the key-map setting properties which may need to be
initialize from the tool settings.
For users that want the 2.7 LMB keymap behavior, this provides a way of
working without tools interfering. For RMB select this operator is quite
redundant with the Cursor tool, we may have to find a solution for that.
Note that we also might later add transform tweak to the transform tools,
when nothing is selected. But this is important for existing users who
preferred the existing workflow.
Both the active tools and selection are now on LMB, which leads to
various conflicts.
For that reason the LMB keymap now has a couple of differences
compared to before. These changes do not affect the RMB keymap.
* Context Menu: W -> RMB
* Select Tool activate: None -> W
* Set Cursor: RMB -> Shift+RMB
* Loop Select: Alt+LMB -> double click LMB
* Mask Feather Vertex Slide: Shift+RMB -> Ctrl+Shift+RMB
* Node Select: only with LMB now, no RMB
The idea behind the W key Select Tool shortcut is that various
tools can't be combined with selection, unlike the RMB keymap.
So this works as a quick shortcut to drop a tool
and go back to selection.
Tools: set Select Box tool as default, rather than Cursor.
This goes along with coming LMB select keymap changes,
where we want the user to be able to LMB click to select by default,
rather than set the cursor.
The cursor will still be directly setabble with shift+RMB.
Previously the brush names were used which had the limit that:
- Brush names that were deleted wouldn't show up in the toolbar.
- Naming collisions between user defined brushes and existing tools
broke tool selection.
Now brushes are created as needed when tools are selected.
Note, vertex/weight paint combine tool and blend modes,
this should be split out into a separate enum.
- Use ctrl for de-select since we may want to use shift for extend.
- Use cursor tool by default,
it's agreed lasso select isn't accessible from a shortcut by default.
It was a bit odd that the scene was stored per window but not the view
layer. The reasoning was that you would use different view layers for
different tasks. This is still possible, but it's more predictable to
switch them both explicitly, and with child window support manually
syncing the view layers between multiple windows is no longer needed
as often.
