This enables us to do more intelligent distribution than simply doing the
rounding on each individual items geometry (which often leads to larger
spacings than specified).

Instead of doing the rounding on the output geometries, we now do the
snapping inside the layout engine. This allows us to do more intelligent
distribution of items, and spacings should always be respected.

There are some cases where items with fractional size hints might overlap
with less than a pixel.  This was also the case before this patch. Those
cases are impossible to fix properly, since fractional size hints
conflicts with the snapping in some cases.

(Fractional size hints is normal for Text items.)

Previous errors in versioned function classes for OpenGL versions
prior to 4.4 have also been fixed to comply with the new OpenGL
xml specification. Such mistakes were due to either bugs in the
old plain text specification files or problems due to the
difficulty in parsing the old spec files.

In some cases this has meant adding in missing functions that were
absent previously.

The other class of problem was when functions were erroneously
included in the versioned function classes when they should not
have been present. That is, some core profile classes incorrectly
had member functions for deprecated functions that should only
be present in the compatibility profile classes. In these cases
these incorrect functions will now trigger a qFatal if
called. This is fine as any applications that called these by mistake
in the past would have been dereferencing a null pointer as the
function pointer resolution would have failed for these functions.

[ChangeLog][QtGui] Add version function classes for OpenGL 4.4 and 4.5
and deprecate some erroneously classified functions.

Try making it compatible with QOpenGLContext::functions() which returns
an already initialized QOpenGLFunctions.

Unfortunately we cannot make them 100% compatible because functions()
conveniently requires that the context (or a sharing context) is current.
versionFunctions() has no such requirement and we cannot safely introduce
it anymore.

What we can do is to state that as long as the context is the current one,
the initializeOpenGLFunctions() call can be omitted. If another context (or
no context) is current, the call will still be needed, like it is today.

Also, we require that the exact same context is current. Sharing does not
count since the exact behavior of sharing contexts with different versions
is unknown.

[ChangeLog][QtGui] initializeOpenGLFunctions() no longer needs to be called when
querying a versioned function wrapper object via QOpenGLContext::versionFunctions().

Historically, the screen number of a QWidget was stored in
QTLWExtra::screenIndex which came in via the Q_WS_QWS platform.
The variable contained the screen number of the QDesktopScreenWidget
and the desired screen number for widget creation (from parent widget
or desktop parent widgets) and was not updated according to widget
geometry or when the associated QWindow moved to another screen.

Storing the screen number is problematic in Qt 5 since it may change
when the list of QScreens in QGuiApplication is rearranged.

This change renames it to initialScreen and changes its usage to only
contain a screen number when a screen is requested by parenting
on a desktop widget or reparenting. A value of -1 indicates no screen
is requested and the number should be deduced from the geometry.

For the usage in QDesktopScreenWidget, add a method to determine the
number via index in the list of QDesktopWidget.
