Fixed bitmap drawing in GL 2 engine when not using GL pixmap backend.

QPixmap shouldn't return true in hasAlphaChannel() for bitmaps, instead
the paint engine should check whether the pixmap is a bitmap or not. In
addition, QBrush::isOpaque() returned true for bitmap brushes, which is
wrong according to the documentation.
