A couple of problems with the ruler:
- the rotated text doesn't look very well at all and interpolation doesn't
help it much
- measuring towards the right most part of the profile makes the text go
out of the screen
To solve these issues and attempt to improve the ruler this patch does the
following:
- place the text at the bottom of the lowest of the start and end points.
this way the line will never intersect with the text
- clamp the x position, so that the text doesn't ever leave the screen
horizontally
- place a white background behind the text so that it will cover text and
graphics under the ruler item
(TODO: place the ruler on top of everything else)

The ruler is a weird beast - it has two child objects that access the
parent to call another function, that call the child functions.
When I updated the plot_info I didn't take that into consideration, what
happened is that when I set the parent's plot_info, the children's
plot_info are still invalid, but the update method is called anyhow.
This patch updates all plot_info's before calling anything else.

I know everyone will hate it.
Go ahead. Complain. Call me names.
At least now things are consistent and reproducible.
If you want changes, have your complaint come with a patch to
scripts/whitespace.pl so that we can automate it.

This changes the ruler a bit, I hope nobody gets offended by it. :)
The main issue is that the scene is now 100x100 pixels wide, so the font
was *really* huge. and setting itemIgnoresTransformations on the ruler
broke a lot of stuff.
I removed the code that painted the text and created a QGraphics TextItem
for that - that will hold the text for the ruler.
Then I played with the view to get the correct angle of the line, that was
in scene coordinates and thus, could not be used directly on the item that
had ignore transformation changes.

This patch just creates two files for the rulerItem, a .h and a .cpp.
nothing was done to make it visible on the new profile yet - will do that
on the next commits
