QColorVector and QColorMatrix are default-constructed following the
Qt philosophy of types always being well-defined. The corner-case where
we need uninitialized versions of these types for performance reasons
is handled explicitly.

BT.2020 is an HDR color space and its luminance range doesn't match
that of the rest of the currently available color spaces. Without
support for white-point luminance in 5.14, there would be a behavior
change when luminance support is later introduced, so it is better to
remove it now, and reintroduce it when the necessary handling of
different luminance levels is available.

Adds QColorSpace and QColorTransform classes,
and parsing of a common subset of ICC profiles
found in images, and also parses the ICC profiles
in PNG and JPEGs.
For backwards compatibility no automatic color
handling is done by this patch.
[ChangeLog][QtGui] A QColorSpace class has been added,
and color spaces are now parsed from PNG and JPEG images.
No automatic color space conversion is done however, and
applications must request it.
