Addresses regression in arrayViewPanel (commit here) where hx, hy never get assigned for line profiles (width=1) .

Is this a bugfix or an enhancement?
bugfix
Proposed changes:

• call do.GetSliceSelection() for line profiles (width=1)
• round to get pixel identity rather than casting to int, which is a floor operation.

>>> lx, ly, hx, hy = do.GetSliceSelection()
>>> do.GetSliceSelection()
(0, 0, 0, 6)

while

yields

>>> (xi, yi, xf, yf)
(0, 0, 1, 1)
>>> image.data_xytc[xi:xf+1, yi:yf+1,0,0]
array([[ 0.25463662,  2.1478719 ],
       [ 1.99672588, -1.52296621]])

There are some remaining quirks:

• displayOptions.GetSliceSelection returning start, finish, and us calling things lx, hx is fairly misleading and requires a +1 for the finish to get the full extent.
• There appears to be a bug in PYME.Analysis.profile_extraction import extract_profile when drawing along the edge of the frame.
