Calendar: weekend columns are wider than weekday columns

[Adam Peller]

All 7 columns should be equal. Any clues how to remedy this? I'm wondering if the new arrows made this more obvious.

in an attempt to align the images on all browsers centered above the weekend TD's, weekdays may be +2px ... revert margin-left and margin-right in .tundra .dijitCalendarIncrementControl .dijitCalendarIncrease/Decrease to fix. tomato/tomato: which looks better, slightly wider weekend nodes with visually centered icons, or unified width calendar nodes, with oddly offset icon nodes. this refs #3661

FWIW, I'd strongly lean towards equal column widths for the days and a header row that's independent of those column widths. I think that is more intuitive and gives more flexibility for skinning and i18n (think of creating a large calendar with full day names and large boxes for scheduling based on _Calendar, for instance)
