core: Resize filters with group layers

Browse source 
Resolves #11054

NDE Filters clip to the size of the layer when
applied. Group layers get their dimensions from
the largest layers under them, so an empty
layer has dimensions of 0 by 0. This means a
filter applied when the layer group is empty will
be clipped to 0 by 0 as well.
This patch adds code to refresh the filter's crop
whenever the group layer is resized by a
layer being added or removed.
