TabContainer: Several bugs when adding tabs programatically

[guest]

I noticed the problems in test_TabContainer_remote.html . - When adding a tab , and selecting different tabs , the css styles won't always change as they should to selected , not selected .
- When adding more than one tab , the new tabs will have 1px cutoff in between the button and the tab area
- When adding more tabs , so that a second line of tabs i required , the first tab showing up on the second line , doesn't create a second line , it just overlaps the content . The same tab also doesn't show up at the start of the first line , instead shows up somewhere in the middle
- When adding even more tabs , the second line gets created but tabs are still starting from the middle

Testing this, it appears to be a race condition for layout() calling TC.layout() after wrapping the first tab.... fixes the 2nd row immediately.... Alignment... I dont have a good CSS tool to play with here (just FirebugLite?)

I noticed another drawing bug when programatically adding tabs to an empty tab container. See attached tabtest1.html for example. It looks slightly different in firefox 2.0 (windows) and IE6, but neither draw it correctly.

will attempt rewrite of TabContainer? layout in 1.2. look at this then.

tk, can you reproduce the original problem? Multiple tab rows appear to wrap properly in trunk. I can only see the error in the test case included here.

(In [15137]) Fixes #5821, fixes #7594: programatically adding tab to empty TabContainer? fails. Problem was that we were querying size of tab strip before any tabs had been created, thus it was coming out as 0.

May also help fix part of #4502 (refs #4502).

the only problem I can see remaining is a missing pixel on the current test. Is there anything else? I'd be inclined to file that as a new, low-priority ticket.
