This is a follow up to ag/32333172. With that change, task thumbnails
are immediately placed in the exploded position and then transformed
into the intermediate positions/sizes that is controlled by the explode
progress.
This CL fixes a glitch where thumbnailView.outlineBounds was not
computed properly. The bounds are now computed per frame (since the task
may animate in from a position that is partially off-screen). The
intersection with the screen bounds rectangle is now done with the
per-frame position of the task window and then crucially scaled to
account for the transformation that is applied to the thumbnail itself.
