QFontEngineS60::boundingBox_const(): The metrics that
CFont::getCharacterData() returns is equivalent to what
TOpenFontCharMetrics::GetHorizBounds() returns. So, remove
the use of TRect glyphBounds, and
TOpenFontCharMetrics::GetHorizBounds().
Implementation of TOpenFontCharMetrics::GetHorizBounds():
http://developer.symbian.org/oss/API_REF/Public_API/file/837f303aceeb/epoc32/include/openfont.h#l1352
QRasterPaintEngine::drawGlyphsS60(): The metrics that
QFontEngineS60::getCharacterData() returns are equivalent to
what QFontEngineS60::boundingBox() returns. So, remove the
use of glyph_metrics_t metrics, and QFontEngineS60::boundingBox().
These changes increase the Fps in
qt\tests\manual\textrendering\textperformance "Latin" from 16.2 to
16.5 Fps on an XM5800. And they do that by removing code :)

If QWidget::destroy() is called (perhaps by setParent) then the window
surface is deleted by the destructor of QSymbianControl instead of in
the "normal" place which is ~QWidget(). This means that we should not
attempt to use the RWindow in the window surface because it is in the
process of being destroyed.

The QS60PaintEngine should not assume that the pixmap is always of type
'Raster'. It should check the classId and if it is not 'Raster' it
should forward the call to QRasterPaintEngine which already handles
this scenario by converting the pixmap to a QImage and drawing that
instead.

We should only add to rendered_spans once, before freeing the rasterizer

When rasterization in the gray raster fails due to out of memory there
might already have been a number of spans flushed. To avoid flushing
these spans multiple times and thus getting overdraw artifacts we need
to keep track of how many spans to skip when we redo the rasterization.

TPos needs to be 32-bit, not 64-bit. QT_FT_Pos being 64-bit caused
sizeof(TWorker) + sizeof(TCell) in qgrayraster.c to exceed 4096, which
is the MINIMUM_POOL_SIZE, leading to rendering errors in certain cases.

Change c46688b8a88da made us use m_curve_threshold for both
QBezier::shifted and QBezier::toPolygon, and adjusted the threshold
dynamically based on the painter scale. Since the threshold in shifted
was already relative to the pen width, it is independent from the
painter scale. Instead, we need to set a separate threshold for dashing.
Also, in several places we were calling setCurveThresholdForTransform
with the painter matrix even though we were transforming the points into
device coordinate space before stroking.

Change 4c515ceb fixed Intersect and Unite-clipping after doing
setClipping(false), but also introduced a performance problem.
If there was no pre-existing clip we'd convert IntersectClips to
ReplaceClips, which is unnecessary since the paint engines already
handle this correctly.
IntersectClips can be handled much more efficiently in the OpenGL 2
paint engine for example. We only need to convert to ReplaceClip when
someone has used setClipEnabled(false) which is anyways expensive and
not recommended.

The gray raster uses long to ensure having 32-bit integers since it was
originally designed to work on 16-bit platforms as well. On 64-bit
platforms switching to use int instead of long gives a performance boost
of ~10 % or so depending on the use case.

Change 7c673a4cf64ba04 introduced some autotest failures in the
fpe_steepSlopes test in QPainter.
Since the other rasterizers all deal in a 26.6 fixed point coordinate
space we should snap the line vertices to this to prevent floating point
overflows due to very steep slopes.
This also necessitates keeping track of four different slope / inverse
slope increments for each of the four edges.
This also fixes a previously QEXPECT_FAIL'ed test case.

With a large pen width and a small scale, due to the hacky way we draw
points (stroking a line from (x, y) to (x + tiny_amount, y)), we some
times end up snapping these two points to the same in rasterizeLine().
If we instead apply the SquareCap before we do clipping / snapping we
don't get this problem.

Our glyph caching system doesn't take GL texture size limitation into
account, and assumes you can create an infinitely large texture.
On top of that, the cache will never create a cache that is wider
than 256, or QT_DEFAULT_TEXTURE_GLYPH_CACHE_WIDTH, which means we'll
hit the texture size limit even faster. With this patch the entire
texture is utilized. However, to fix in properly we need to support
having multiple texture for each font engine. That will be fixed
shortly (see task QTBUG-13784).
