ginga - Ginga v4.0.0

• fixed getattr functionality in Bunch
• removed the "mock" backend; use "pil" backend for similar purposes
• fixed a longstanding issue where events registered on a canvas could be masked by default key/cursor bindings (not associated with a mode). This meant, for example, that only certain keystrokes could be captured by an event handler registered on a ginga canvas, because any keystrokes that had a default binding would take precedence. Now such bindings are only executed if the event is not handled by any active canvas bindings.
• Removed the "Quick Mode" and "From Peak" options in the Pick plugin to simplify operation.
• Many deprecated camelcase (non-PEP8) methods were removed. Use the "snake-case" names instead.

• Refactor modes from Bindings module into separate modules:

  • modes can now be written and understood as having a very similar structure to a plugin.
  • mode docstrings can be written and maintained better to document the modes and the code implementing a mode is much easier to understand since it is encapsulated rather than all mixed together in one huge file.

• ScreenShot now correctly captures the background color of the viewer

• Fixed a DeprecationWarning related to use of entry points

• ColorMapPicker plugin can now be launched as a local or global plugin

• The keywords save_primary_header and inherit_primary_header in the AstroImage constructor are deprecated. Use these same keywords in AstroImage.load_hdu() or AstroImage.load_file() methods instead. Several other methods in AstroImage are deprecated as well; they were previously pending deprecation.

• Fixed an issue where image might not be redrawn properly if scale or pan is set directly via a viewer's settings object (not the usual case)
