This is mostly straight-forward, but some things are worth noting:
1. Yes, this is necessary. The noexcept operator looks for noexcept tagging,
not at the contents of the function to determine whether to return true.
The more conditionally-noexcept functions are used, the more important it
becomes that low-level classes are correctly marked noexcept. In that, it
is like constexpr.
2. In accordance with the rules governing noexcept specifications for the
standard library itself, the get*() functions, as well as any function
taking (but not returning) channel values as ints or qreals, or taking
QStrings are not marked as noexcept, since they have preconditions and
thus a narrow contract. Narrow-contract functions should not be noexcept.
All other functions have wide contracts (ie. no preconditions).
3. Any function returning QString can throw (bad_alloc).
Consequently, they, too, are not marked nothrow.

This fixes the rendering of translucent borders on CSS-styled widgets to
prevent visible overlapping at the corners. This is done by using a
miter joint (45 degree angle) if either of the adjacent edges are
translucent. Previously, adjacent edges would be drawn at full length
and overlap at the corners if both edges are BorderStyle_Solid and have
identical QBrush objects. This works if both QBrush objects are opaque
but causes visible overlap if one or both of them are translucent.

Instead of creating a QByteArray, possibly normalizing a leading
'--' (one allocation, plus possibly one copy), simply use the
old 'ol str(n)cmp, skipping the first character if the argument
starts with '--'.
It also fixes parsing of -stylesheet and other options which
were erroneously parsed using indexOf() != -1, when they
should have used startsWith().
Also saves 504/742/522b in text size for QtCore/QtGui/QtWidgets,

Both constructors were taking a pointer, so they participated in
overload resolution along with QTextDocument and QTextFrame pointers.
Instead, make them take references and move them to the private section
of QTextCursor. That necessitated adding a method to QTextCursorPrivate

On some drivers (e.g. NVIDIA, tested on Windows) the
status check is apparently expensive. A simple FBO
test app rendering into the FBO on every frame (and
thus calling bind()) shows a 19-21% CPU usage. With
the patch this gets reduced to 0.8-1%.
The check is fairly useless too - whenever creating
attachments, the status is checked, so d->valid is
up-to-date.

offset telling the position within the top-level widget. The size is
usually different (smaller) than the tlw's size as well.
An unfortunate optimization attempt led to ignoring the size for native

artifacts whenever such widgets were placed in the top-left corner of
the toplevel. This is now corrected.
