QTextEdit: layout problem with text frames and floating text

There are layout problems in QTextEdit related to text frames, where text flows along the right hand side.

• The yellow background of the text block floating at the right hand side of the frame covers part of the frame.
• The left margin property of the text block is not obeyed when floating beside the frame.

Example program:

#include <QApplication>
#include <QTextEdit>
#include <QTextCursor>
#include <QTextFrameFormat>

int main(int argc, char* argv[])
{
QApplication app(argc, argv);
QTextEdit edit;

QString text = "Test Test Test Test Test Test Test Test Test Test Test "
"Test Test Test Test Test Test Test Test Test Test Test.";
edit.append(text);

QTextCursor c = edit.textCursor();
c.movePosition(QTextCursor::End);

QTextFrameFormat ff;
ff.setBorder(1);
ff.setPosition(QTextFrameFormat::FloatLeft);
ff.setWidth(120);
c.insertFrame(ff);
c.insertText(text);

c.movePosition(QTextCursor::End);
c.insertBlock();

QTextBlockFormat bf;
bf.setBackground(Qt::yellow);
bf.setLeftMargin(10);
c.insertBlock(bf);
c.insertText(text);

edit.show();
return app.exec();
}

Note: This requires bigger changes in the layouting process to obey frame ordering.
