Change the prevent blitting counting

Attaches is a patch that fixes the counting of widgets that prevent blitting.

Each ScrollView counts how many widgets it and its subview have that prevent
blitting. Adding a new widget thus increments the count for all parents.

When an scrollview containing such widgets is detached, its count is
substracted from its former parent (and its parents).
