Linus Torvalds 01e8984d7d Create tool-tip with depth/pressure for the whole profile area
This extends on our current tooltip logic (which shows events when you
mouse over them) to show tooltips for the whole profile area.

If you mouse over an event, that is still shown in the tooltip, but
even in the absense of events, the tooltip will be active, and mousing
over the profile area will show the time, depth and pressure.

This can certainly be improved upon further, but even in this form it is
useful.

Fixes #9
