Details:

(provisionally OS set to Windows, haven't yet checked Linux)

After zooming in on an otherwise fine plot it turns out that annotations
extend beyond the "plot box". 
In the attached figure (a geological cross-section with boreholes) the plots
themselves (colored vertical lines = layering) are clipped at the plot box
borders, while the labels corresponding to clipped boreholes are drawn outside
the box limits.
In this case they extend beyond horizontal limits but vertical plot box limits
are also ignored.

This happens with Qt and fltk toolkits.

Expected: labels to be clipped at plot box limits as well.


In addition, while I have set "axis tight" on these plots, it turns out that
after zooming in horizontally the left and right plot borders aren't exactly
"tight" to the plot window limits. But I do not know if "axis tight" is to be
preserved when zooming in (?) - As a user I'd expect so but maybe this works
as intended?
