When building docs for the mac, qdoc comments for functions defined
in the .h file were not found in any of the .cpp files in the mac
package because they were in the x11 or windows .cpp file. So I
moved them to a .cpp file that is in all the packages.

Don't know why the X server crashes, but it's reproducible both by us
and customers so we should fall back to the raster paint engine to avoid
the crash.

Images coordinates should simply be rounded and are not to be subject
to the aliased coordinate delta. The patch also adds a tiny delta in
QSpanData::setupMatrix() to ensure coordinates for fetching from source
images are rounded the opposite direction of the target rectangle.
This removes a lot of artifacts when trying to do border-image based
drawing on non-integer coordinates. A new qps test for border-image
drawing is included.

The bug appears in the raster paint engine and only in release mode as
the cause of the bug is in the MMX and SSE blend functions which are
disabled in debug. To prevent it simply we return early if we detect
that we have an opacity of 0.

The width of a pixmap is NOT the same as the bytes per row. We may have
been able to do that in the past, but it doesn't work in the general
case. I also took the liberty to introduce a QCFType to automatically
handling the free in the general case.

We can speed up the calculation by using rect intersections
if possible, i.e. QRegion &= QRect instead of QRegion &= QRegion.
Then we'll get rid of one QRegion construction and the intersection
itself is slightly faster.

Addendum to change 9b674ddcea7c0ff7912f185474b7d98bc83bd39f.
The problem was that QWidget::paintEngine() (pure virtual) was
called while being in the destructor. The use-case itself
(see above change) is very very corner case, but still,
it shouldn't crash.

Introduce Q_WS_WINCE for Windows CE only windowing parts. So far we
decided to stick with Q_WS_WIN32, but having a separate define
makes the code more readable. In addition Q_WS_WINCE_WM is available
for Windows Mobile only parts, where we do not check for the OS on
runtime.

QGLWidget does not support partial updates unless the context is
single buffered and auto-fill background is disabled. The problem
was that QPaintEvent::region() returned the requested update region
without taking into account the limitation of QGLWidget. If QGLWidget
doesn't support partial updates, it means everything has to be updated,
and QPaintEvent::region() must return the whole widget rect.

an untransformed painter
When passing a painter to QWidget::render, we use the
painter->paintEngine()->systemClip() as the "system viewport",
i.e. all painting triggered by render() should be limited to
this area. The only way to achieve this is by always ensuring the
system clip is clipped to the same area (systemClip &= systemViewport).
The problem however, was that we only did this for transformed
painters. We must of course always do it when there's a systemViewport
set, regardless of whether the painter is transformed or not.
Auto test included.

QPainter inherits some properties from the widget, among other font and
pen. These are set in the painter's state in initFrom(), but in 4.5 we
forgot to call QPaintEngineEx::penChanged() to let an extended paint
engine know that the pen has changed. This caused the raster engine to
believe it could blit non-opaque text, due to the fast_text flag not
being correctly updated.

QPrinter::printerName() used to return the CUPS printer queue name instead
of the user-set printer name, which was wrong. In addition, if trying to
set the printer name to a non-valid printer, the default printer was still
used internally, which is not correct. As sonn as an invalid name is set,
the printer now enters an invalid state, which it can only get out of
by setting a valid printer name.

Implement the alphaRGBMapForGlyph function and make use of it in
the raster engine. The gamma correction is currently hardcoded to 2.0
which looks very good on two separate displays (iMac and MacBook Pro).
Ideally this would be picked from the system settings or computed
dynamically, but as long as 2.0 works, we'll stick to that.
