QColorConstant is a C++11 version of Qt::GlobalColor, except that instead
of Qt::red being an enum, QColorConstants::red is an actual QColor instance,
a bit like in the Qt 3 days.
In addition, the SVG names that QColor understands are also available,
with the same values. Technically, when building a QColor from a color
name, QColor ignores casing and whitespaces; we stick to the SVG/CSS
official color names (which are lowercase), and prefix them with Svg
to clarify where they come from. For instance, note how SVG's gray
is not Qt::gray.
[ChangeLog][QtGui][[QColor] Added QColorConstants, a namespace
containing constexpr QColor instances.

Replace our use of 'gamut' with 'primaries'. One is the axes of the
color space, the other the volume of representable values. For the
currently supported color spaces those are mostly equivalent, but when
we later add support for scRgb, this would be misleading as it has the
same primaries as sRGB but a much wider gamut, and we would like to use
the same primaries/"gamut" id for it.
Also few people would know what "the sRGB gamut" is, but
"the sRGB primaries" is easily googable.

The newly introduced clear() method left the path in an undefined
state: d_ptr allocated, but no elements. The elements vector is
otherwise never empty, since ensureData() inserts a dummy initial
moveTo element.
Fix by making sure that clear() leaves the path in the same state as
ensureData() (i.e. "empty" but not "null"), except possibly more
capacity allocated in the elements vector.

The QBrush constructor taking a QGradient would assert or crash if
passed a null (NoGradient) gradient. But it is not necessary for the
API to be as brittle as that: instead the result can simply be a null
QBrush object, i.e. the same as the default QBrush() constructor
creates (style == NoBrush).
This issue comes up now since with the recent introduction of
QGradient presets, the API opens for using QGradient directly, whereas
earlier, only the subclasses QLinearGradient etc. were to be used.

We translate all pure gray colors into cmyk having c,m,y=0 and only
the k value expressing the darkness. But a fix introduced to avoid
division by 0 caused rgb(0, 0, 0) to be an exception to this; it ended
up being translated as c,m,y,k=1 instead.
Fix by catching the potential div-by-0 situation earlier and directly
set the orthodox cmyk translation: c,m,y=0,k=1.

the pixel of the join point in the corner, while the latter by
coincidence used to paint the same pixel as a cap because of the bug
