Stephan Aßmus f466d35d9c Rewrote parts related to drawing the labels. The order of drawing happens as
this (seems to be what R5 BStatusBar does):
* combine the "trailing text" with the "trailing label" and truncate the
  resulting string on the left side according to the width of the entire
  control
* combine the "label" with the "text" and truncate that on the right side
  according to the space left by the right hand text.

-> No more overlaps (theoretically, in practise there are still overlaps
  because our BFont::TruncateString() does not respect the width in some
  situations.)

* Changed _SetTextData() accordingly, it is not used anymore for the
  label and trailing label, and could therefor be simplified a little.
* fixed _BarFrame() to not return fractional coords, which could sometimes
  leave a dirty line of pixels.
