The resize event should not be used to draw, as there will be a follow-up
exposeEvent delivered just after, and we don't want to draw twice.
This is how QRasterWindow operates too, except it defers the backingstore
resize to beginPaint() instead of resizing in the reizeEvent.
It's also how QOpenGLWindow operates, which also has a note for the
virtual resizeGL method saying: "Scheduling updates from here is not
necessary. The windowing systems will send expose events that trigger
an update automatically."

When reading an HTML file with <H1> for example, we still set the font
size as before (that's how it always was done),
but now it remembers that it came from an H1 tag, so it writes
<h1 ...><span font-size:xx-large ...> ... rather than
<p ...><span ...> ... This will help with the upcoming Markdown
format, where heading level is saved but the font is not.
Now the style combobox in examples/widgets/richtext/textedit can set
list item type, heading type or "standard" formatting, and also shows the
current formatting of the line that has the cursor. It was always a
shortcoming in this example that it only allowed setting the current line's
block format but had no feedback to show the current format.

QTreeView makes columns movable except for the first one
(since Qt 5.0, see commit e0fc088c0c). This is indeed best
for actual trees, but not when using QTreeView as a flat
multi-column list (with no "root decoration"). Then it should
be possible to move the first column.
[ChangeLog][QtWidgets][QHeaderView] Flat treeviews can now allow
the user to move the first column (like in Qt 4.x) using the new
method QHeaderView::setFirstSectionMovable().
