after-insert

Called after a snip is inserted into the buffer (and after the display is refreshed; use on-insert and begin-edit-sequence to avoid extra refreshes when after-insert modifies the buffer).

• (send a-wx:media-pasteboard after-insert snip before x y) -> void
      snip : wx:snip% object
      before : wx:snip% object or null
      x : inexact real
      y : inexact real
