Gnats 5911: SCT: When 'Sheets' are used, the 'Go To' function doesn't always scroll correctly to the picked slot divider.
Bug Number: 5911
Release notes (y/n): Yes
For Release Nums: 7.0.5

In vertical time axis orientation of the SCT series data tab (where slots 
are shown as columns), the slot divider column picked under the 'Go To' 
menu sometimes winds up on the _right side_ of the SCT, instead of the 
_left side_.  As a result, only the slots _before_ the divider become 
visible -- rather than the slots _after_ the divider.

See this image: (this will be edited with the image page).

This occurs only in SCTs using SCT sheets, and when a sheet other than 
the "All Slots" sheet is selected.  The problem behavior depends also on 
the horizontal scroll position of the SCT before using the 'Go To' function.
The internal cause is related to the use of column-hiding in the SCT sheets 
implementation.

See the fix in method: SctView::scrollToCol (int col).
