Commit d3dcc6f introduced a regression to QTextEdit, leaving
it to always show the cursor regardless of focus. The reason
is that QTextArea used to toggle visibilty by setting the
cursor blink rate. What it really wanted to do was to set
cursor visibility explicit.
This patch implements function setCursorVisible, and updates
the places that used to call setBlinkingCursorEnabled to
instead call setCursorVisible (where it makes sense).

Recent changes to the xcb platform plugin added logic to paint to a
server-side X Pixmap when the MIT-SHM extension is unavailable. Those
changes also added logic to keep track of the dirty areas that need to
be flushed to the server from the backing store when the backing store
is flushed to a window.
Because a single QRegion was used to track those areas, nested paint
operations no longer accurately tracked all the dirty areas. Consider:
void Widget::paintEvent(QPaintEvent *) {
QPainter p1(this);
for (int i = 0; longRunningOperationInProgress(); i++) {
QPixmap pixmap(size());
QPainter p2(&pixmap);
p2.drawText(pixmap.rect(), i & 1 ? "Working." : "Working..");
p2.end();
QBackingStore *bs = backingStore();
bs->beginPaint(rect());
p1.drawPixmap(0, 0, pixmap);
bs->endPaint();
bs->flush(rect(), windowHandle());
}
p1.fillRect(rect(), Qt::red);
p1.drawText(rect(), "Done!");
}
While this code could be restructured, it is a common pattern in legacy
Qt applications which cannot be easily changed.
