Comment 1 for bug 1250221

On Brian Murray's demand, I'm adding some information about the bug LP #1089052:

* Impact:
in docks, icons can be aligned (to the middle, right or left of the screen's border)
in "panel" mode, separators expand to fill the screen width (which separates icons in distinct groups), but when there is no separator, all icons are grouped togather, and in this case, they didn't respect the alignment parameter.

this can be quite annoying in some cases
for instance, this prevents the user from being able to move the icons away from the top-left corner of the screen, which is where window's controls are on Ubuntu.

The fix was to correctly take into account the alignment in this particular case.

* Test Case:
create a dock with an icon inside, set this dock with the "panel" view, and then try to change the alignment to the right: it won't work

* Regression Potential: it only concerns the position of icons in docks with "panel" view and no separator in the dock, which is by itself not a common use case.
we checked that it didn't influence the placement of icons when there is at least 1 separator, and that icons can be placed on the left, middle and right when there is no separator.
