explicit value for box width relative to immediate parent

[astooke]

Hi,

First of all...thanks for snakeviz, it's super helpful!

The one feature I find myself looking for over and over is to see an explicit value which relates the width of a box (thinking icicle mode) to it's parent, rather than just the total time across the program. @jiffyclub you hinted at this in a comment in #72. It could be in units of seconds or a percentage. It seems like this value must already be available somewhere, to render the boxes, but it's not presented anywhere in the GUI?

Unfortunately this information is not available in the profile data, I wish it was. 😞 When a function is called multiple times in different parts of the call tree its size relative to parents is basically fudged and can be in inaccurate. See #112 for an example.
