According to Windows docs, GetMessage() function retrieves the messages
from the input queue in defined order, where posted messages are
processed ahead of input messages, even if they were posted later.
Therefore, if the application produces a posted event permanently, as
a result of processing that event, user input messages may be blocked
due to hard CPU usage by the application.
It's not a problem, if an internal Qt event loop is running. By calling
sendPostedEvents() on the beginning of processEvents(), we are sending
posted events only once per iteration. However, during execution of
the foreign loop, we should artificially lower the priority of the
WM_QT_SENDPOSTEDEVENTS message in order to enable delivery of other
input messages.
To solve the problem, it is proposed to postpone the
WM_QT_SENDPOSTEDEVENTS message until the message queue becomes empty,
as it works for the internal loop.

As an option. Must opt in via setting ExternalContentsInPass in
the flags for beginFrame(). It is somewhat unfortunate to require
declaring this up front, but forcing using secondary command buffers
always, even though beginExternal() may not be used in many applications,
would be an overkill.

Mainly for Vulkan where it lacked the recording of the still queued
commands. Uncovered by Qt Quick examples that integrate custom Vulkan
rendering.
This still has an issue that needs to be tackled separately. (we probably
will switch to using a dedicated secondary command buffer with
RENDER_PASS_CONTINUE_BIT for the external commands, and then just have
a vkCmdExecuteCommands in our own queue instead of recording everything in
beginExternal).
The possibility of losing glMemoryBarrier() calls due to begin/endExternal()
with the OpenGL backend is fixed too. The logic here mirrors Vulkan
to some extent except that we do not have a concept of (and so the trouble
with) renderpass instances.
Clean up around the implementations of finish() as well. Attempting to share
code via a "flushCommandBuffer" function is admirable but is not worth it
since some semantics are different. (finish() cannot be called within a
begin/endPass, unlike begin/endExternal).

If an item is double clicked, then without this fix, the views emit the
clicked() signal when the mousebutton is released after the double click
event. This is unexpected and wrong.
QAbstractItemView keeps track of the item the mouse was pressed on, to
verify that the release occurred on the same item before emitting
clicked, and to make sure we have a valid pressed item before initiating
drag'n'drop. By resetting d->pressedItem when a double click has been
handled, we can prevent the emission of a clicked signal in the next
release event.

QColorConstant is a C++11 version of Qt::GlobalColor, except that instead
of Qt::red being an enum, QColorConstants::red is an actual QColor instance,
a bit like in the Qt 3 days.
In addition, the SVG names that QColor understands are also available,
with the same values. Technically, when building a QColor from a color
name, QColor ignores casing and whitespaces; we stick to the SVG/CSS
official color names (which are lowercase), and prefix them with Svg
to clarify where they come from. For instance, note how SVG's gray
is not Qt::gray.
