<!--{{{ Naming Scheme for Labels and Tooltips

General

  * Use Unicode, not ASCII
    * Ellipsis (…), not three full stops (...).
    * Curly apostrophe (’), not typewriter apostrophe (').
    * Use curly quotes (‘’ and “”), not typewriter ones.
  * Use en_US spellings.

Labels

  * Typically <verb> [<target>]
  * Title case, imperitive mood "Open Brush…", "New Curve", etc.
  - No trailing full stop.
  - Trailing ellipsis if immediate user input is needed to complete the action.
  - If the object of the action is the main canvas, omit the target
  - Similarly, omit "current" or "active" if it's not confusing.
  - (You can probably omit the article "the" too, in this case)

Tooltips

  * Don't just repeat the label with more verbage. Explain it.
  * Imperative mood, 
  * Sentence case, with a trailing full stop.
  * Use Unicode, not ASCII
  * The accel map editor only shows an action if it has a tooltip.
  * (Omit tooltips on things like the entry we need for a submenu)
  * The "tooltip" field is really mostly used for tthe accel map editor now.
  * Menu items don't really have tooltips, so menu paths to tooltips can be omitted from the context.

Vocabulary

    * "Canvas": a document, treated as a surface to work on (="Page")
    * "[Your] work": a document, treated as what the user has done.
    * "Brush Shortcut Key": memory slots for brushes accessible via keypress
      - sometimes referred to as "contexts" in old names
    * "Painting Color": the color used for painting.
    * "Paint Mode": the brush blend mode, how pixels are applied.
    * "Dockable panel": widget that can be docked into a sidebar or split out.
