Mark default as prevented and check for prevention of
default when handling mctDrop events (which allow
views to follow up on drop gestures by positioning
objects within themselves) avoiding redundant drops
into embedded views. WTD-1233.
When switching among domain objects and/or views, avoid
reusing the same information is scope. The wrong information
in scope can cause various failures in views, such as WTD-1182.
Update frame positions when model.composition changes,
instead of when model changes. Ensures correct display
after changes to avoid redrawing on every update,
WTD-716.
Add a commit function to scope from the edit representer;
this avoids issues trying to transparently detect and
persist changes made during edit mode, while still requiring
only minimal action from individual views. WTD-535.
Store changes to the size and position of panels in a
layout to its configuration. The mct-representation
directive (and its constituent parts) is responsible
for detecting and persisting these changes as
appropriate. WTD-535.
