For certain slightly miscoded png images, newer versions of libpng

There was a false assumption that the bidi level of text is only
used for visualizing the text, not for calculating its bounding
box. But the bidi level is required for shaping (indeed many
OpenType rules check for reading direction) and the glyphs used
to represent a given text may be different based on its
directionality. The effect would be that the bounding rect we
calculated for text would sometimes be too small for RTL text, and
we would end up clipping pixels.

In some situations, this allows for nicer code. It's also possible to
make this constexpr in C++11, whereas the mutable transpose() would
require C++14-style constexpr.
The new function should also be faster, since it just swaps the member
variables.
Because of constexpr-function limitations, the way the return value is
constructed needs to depend on the level of the compiler's C++11 support.
This is not the only class that requires uniform init to provide a fully
constexpr interface (QUuid and QBasicAtomic come to mind), so this should
probably be generalized across Qt at some point.
