Modifying the Layo is not what you need to do... there is a simpler solution. You need to fix PXM#2004 -- the titlebar image. Your problem (as far as I can tell) is that you did not center your left and right endcaps right .... if you look at it, you can see that the right edge of your left endcap (the widget cap) is being drawn on the left edge of the right endcap (the toolbar endcap). Lets say, for example, that your widget cap needs to be 80 pixels wide... this means your toolbar cap needs to be exactly 80 pixels wide as well, so that when you peice your endcaps together for PXM#2004 it splices them directly down the center... that way your titlebar stretch(PXM#2500) draws directly inbetween the caps correctly.

If you need further explanation feel free to contact me... I hope this helps.
