(experimental) slotwise inheritance à la Henry Lieberman for
sprite-local variables.
see
http://web.media.mit.edu/~lieber/Lieberary/OOP/Delegation/Delegation.htm
l
Let a sprite inherit another sprite’s local variables by making it the
“parent” in the sprite-icon’s context menu (the button icon in the
sprite corral underneath the stage). The child not only inherits the
variable slot but also - dynamically - the parent variable’s value.
Changing the parent’s variable value also changes it for every child.
If a child uses SET or CHANGE on an inherited variable it automatically
“shadows” it with its own value, thereby stopping dynamic participation
in the parent slot’s value (in effect dis-inheriting that slot).
Deleting a shadowed variable slot once again reinstates its inheritance
status.
inherited variables are shown as “ghosted” both in the child’s
variables palette and in such stage watchers. “Shadowing” them
un-ghosts both the variable blob template in the palette and the
watcher onstage (if any). Deleting a shadowed variable once again
ghosts the watcher and the palette block template.
Delete a (shadowed) variable either via the “Delete a variable” button
in the IDE or using the new “Delete” block in the variables category

This is essentially the same icon (lambda, yellow w/ brown border) but newly
rendered at 64, 32, 24 and 16px for the best resolution on all platforms.

so Snap reacts to keyboard events right away (without having to click
on the IDE first)
