[PATCH 3/4] Profile: improve tooltip animation

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

Remove a couple of expand() calls(?). Also store the last
expanded rectangle size in the private variable nextRectangle
and use that in collapse() animation. Patch prevents a small
jump/resize glitch if the user quickly hovers over and out
of the profile while the tooltip is still resizing.
