Library: eliminate QPainter warnings

Browse Source 
There were many run-time warnings in YACReaderLibrary built in Debug
mode with hardware acceleration disabled and with ClassicComicsView
as the active comics view:
    QWidget::paintEngine: Should no longer be called
    QPainter::begin: Paint device returned engine == 0, type: 1

The ComicFlowWidgetSW::paintEvent() implementation now corresponds to
ComicFlowWidgetGL::paintEvent(), which has been fixed earlier.

QWidget::repaint() calls paintEvent() immediately.
PictureFlow::paintEvent() calls d->renderer->paint(). So the
d->renderer->paint() call in PictureFlow::updateMarks() was redundant.
