Create the drop indicator in mouseEntered if needed. This is the case where the collection view is a drop destination but not a drag source.
In _updateDragAndDropStateWithDraggingInfo... , handle the special case where the drop destination is 0 (includes item count == 0).
Test app: add an empty collection view acting as a drop destination for the first collectionView.
There is not need to use that much arguments because the result is stored in ivars.
CPCollectionViewItem -copy: set properties correctly even if the collectionView overrides them.
Do not cache removed items in -reloadContent when the item prototype changes.
maxItemSize:
Interpreted as horiz/vertic expandable when zero size and the proto view has a CPViewWidth|HeightSizable. (per cocoa but not documented).
maxItemSize height support.
Fixed: incorrect position when num items < numberOfColumns.
Rewrote layout engine. Splitted the computation of size, columns count, rows count from the actual layout where we set the frame.
This will help when/if we support insertion/mutation of -content or view animations.
We can also be more lazy when the computation results stay the same.
Added shared -init. Whitespace cleaning.
CPCollectionviewCibTest:
Add ability to set the 2 kinds of prototypes, one loading its view from a cib, the other with a view outlet in the same cib.
Loaded protoype: the bound textfield can commit its value to the model.
UI for setting maxNumberOfColumns|Rows min|maxItemSize
