Any Qt application that embeds a QSGView needs to call this
because of the threaded renderer. Today applications that
use threaded GL silently fail. In a few weeks time, the
refactor branch will be merged, which will obsolete this
change, so it is a temporary measure to get tests and
examples running.
If a QWindow has a parent but is top-level the corresponding
QPlatformWindow should not be re-parented but instead be made transient
for the parent window if possible.
The application main window defaults to fullscreen size when initially
constructed, even if softkeys are specified for it, as the screen
furniture is constructed later in show_sys. This resulted in the main
window being partially under softkeys.
Fixed by invoking handleClientAreaChange() explicitly in show_sys in
fullscreen with softkeys case.

Widgets are left in a transitional (and incosistent) state while being
re-parented, which caused QWidget::effectiveWinId() to crash in certain
circumstances. See patch for more details.

We forgot to send the ParentAboutToChange event, which meant QGLWidget
didn't destroy the old EGL surface. This could cause two EGL surfaces to
be created for the same QGLWidget, which leads to undefined behaviour on
some platforms.

The patch moves the global static QSettings object
from QLibrary to QCoreApplication and reduces a

Without the patch, a large Trolltech.conf was

It was previously not possible to render text (QPainter::drawText)
in a secondary thread on Symbian, it always resulted in some
kind of panic. This patch corrects it. For S60 5.0 and earlier
the behavior is not changed, threaded text rendering is only
supported on Symbian^3 and newer. This also means
QFontDatabase::supportsThreadedFontRendering() will return
true from now on, but only on Symbian^3 and higher.

Minimum sizes of widgets can cause windows to expand beyond screen
limits in QWidgetPrivate::setGeometry_sys. Normally this is not
noticeable as the window size is forced in various places to the
clientRect, but there are certain sequences where the size set in
setGeometry_sys is the final one, resulting in too large windows.
Removed the modification of window size in setGeometry_sys
for fullscreen windows for which the correct size is already requested.

This fixes a regression that was created by
75e478abdf336bbdc1b00e2ca4f5293d5455a0cb.
That broke accessibility on 64 bit windows, since lParam can both be
0x00000000fffffffc and 0xfffffffffffffffc.
However, MSDN explicitly says that lParam should be casted to a DWORD,
which would result in (an unsigned) 0xfffffffc in both cases. This can
then be compared to OBJID_CLIENT (defined to ((LONG)0xFFFFFFFC).

This had the following negative effect in qmlviewer:
- Every time the qmlviewer logged something to its QPlainTextEdit
(regardless of if it was visible or not) it would call
updateMicroFocus (because appending to QPlainTextEdit would move the
cursor). The result was that the AT client got overloaded with
accessibility state changes, and response time got really bad.

the main directory hierachy as they won't be
part of Qt5 in any case.
Create a guikernel/ directory that contains the files that'll go

In addition to that image/, painting/ and text will end up
int QtGui.
The SPI_FONTSMOOTHINGCONTRAST macro is not defined everywhere. When

If the SRGB framebuffer extension in GL is available, we can support
gamma correction of text with a gamma of 2.1. On Mac this is
sufficient for gamma correcting subpixel antialiased text. Gray
antialiasing should not be gamma corrected on Mac.
On Windows, the user can potentially set the gamma value to anything
between 1.0 and 2.2 (or something like that). We support anything
that resembles 1.0 closely enough by pushing the text out without
any correction (like before). We also support anything that resembles
2.1 (the gamma hardcoded in GL's SRGB extension) by turning on the
extension before blending the text. In between the two, we'll use
gray antialiasing to avoid differing too much from the raster engine
(which is our reference in this.)
For gray antialiasing on Windows, we use a constant gamma of 2.3 which
has been determined by experimentation. Since this is close enough to
2.1 we do gamma correction with SRGB extension.
The distance limit of 0.2 is determined by some experimentation.
