Occasionally we get regions with bounding rects outside the widget, so
we need to take care to clip against both the native widget and the

The code was mispositioning lines by half a pixel, as it
added half a pixel offset and then rounded in addition.
This submit fixes this and also removes certain artifacts when
drawing rects at .5 pixel positions.
Lance now doesn't show any significant differences to the
4.7 rendering anymore.

When rasterizing two adjacent QRectFs it's important that the shared x
or y-edges have the exact same coordinates, or there might be a hole or
an overlapping pixel when they are rasterized. Since the
drawPixmapFragments API was based on a center position and a scale, it
can not be used for this purpose, as the in the situation of two
horizontally adjacent rectangles the right edge of the left-most rect
and the left edge of the right-most edge are computed differently. Thus
rounding errors can cause them to not be equal, especially when there's
also a scaling / translating painter transform involved.
Thus, to not sacrifice performance, we need to introduce a new
drawPixmapFragments API that's simply takes an array of target
rectangles and an array of source rectangles. It should give a slight
performance boost for the border pixmap use case as well, since there
are less floating point multiplications / divisions involved.

Revert part of hot fix 48ff7e5af99923396243940979d15d4ec2e2730c since
it is no longer needed in Qt 4.8 due to the introduction of a separate
code path for the FreeType case in drawCachedGlyphs(). This is also
explained in the description for that commit. The consequence of the
commit was that subpixel antialiasing would be turned off for all
text drawn with a transformation and the raster engine. In the past
this was not the case, it is however the case in several other paint
engine, so the regression was deemed okay to hot fix the original
problem. In Qt 4.8 the original problem has been fixed properly.

Since Lion, Core Text starts to return fractional values for
x origin in the glyph bounding box. To get correct alignment
we need to make it integer, it seems that round will cut certain
pixels (x = 0.6 will be round to 1, then that glyph will be moved
too much to the left in image glyph cache). Reverting 4297b85a
appears to work fine on previous version of Mac OS X as well.
This change will not affect Windows (DirectWrite) and FreeType
font engines since they both return integer values for that.

QBezier::pointAt() could potentially return values outside the bezier's
bounds, even when the bezier was a straight horizontal line. For
example, with y = 0.5, it would produce y=0.5 or y=0.49999999999999 for
different values of t, which when rounded cause jittering in a QML
PathView.

After discussing the state of the raster engine with many key devs in
Oslo, we have concluded the following:
Switching to raster as default is a big change for Qt-4.8. The
posibilty of introducing regression for 3rd-party applications
are high. From manual testing we can easily spot regressions
ourselves, expecially for text rendering. And the overall drawing
performance seems to drop slightly. So there seem to be no reason
for us to take such a risk at this point in time for Qt-4.8, expecially
since we have other tasks that should get our attention going
forward, and the main person that did the implementation has left.

When drawing such pixmaps (used by both the openvg and opengl graphics
systems) onto another pixmap or to a QImage, the performance was
sub-optimal due to missing and accidentally disabled support
specific to QVolatileImage. This is now fixed and drawing pixmaps into
a QImage is also made optimal by using the QS60PaintEngine for
QImage too. This will cause a 5-7x (or even up to 12x on certain
hardware and platform) increase in offscreen pixmap drawing
performance.

Adding the fallback to QPainterPath for large QStaticTexts created a
regression where all text would be painted in black regardless of the
color you set on it. The color in QStaticTextItem is sometimes invalid,
in which case the current painter color should be used. In either case,
the color is already set on the current pen when entering
drawStaticTextItem() so we can just use that.
