QProgressBar widget are now also painted in liquid style -- this is only

possible by intercepting the paint events, since TT forgot to make this
widget styleable.

 /*
  * This is a fun method ;-) Here's an overview. KToolBar grabs resize to

  * trying to get shaped widgets to work right without masking. QPushButton,
  * QComboBox, and Panel applet handles capture mouse enter and leaves in order
  * to set the highlightwidget and repaint for mouse hovers. CheckBoxes and
  * RadioButtons need to do this differently. Qt buffers these in pixmaps and
  * caches them in QPixmapCache, which is bad for doing things like hover
  * because the style methods aren't called in paintEvents if everything
  * is cached. We use our own Paint event handler instead. Taskbuttons and
  * pager buttons draw into a pixmap buffer, so we handle those with palette
  * modifications. For QHeader, different header items are actually one widget
  * that draws multiple items, so we need to check which ID is hightlighted
  * and draw it. Finally, we also check enter and leave events for QLineEdit,
  * since if it's inside a combobox we want to highlight the combobox during
  * hovering in the edit.
