As the destroyed() signal is emitted from ~QObject, it is not allowed
to use static_cast to a QAbstractButton on that pointer anymore.
And the qobject_cast will also fail which will keep a dangling pointer
in the hash.

The color values of ppm and pgm images can be either 8 or 16 bits.
They can also be scaled to a smaller max value, and they can be
expressed either binary or ascii. For some of these permutations, Qt's
image handler lacked implementation or would decode the wrong color
value. This commit fixes that.

In fe97ecf408 we added support for
arbitrarily sized glyphs, since there is no guarantee that a glyph
will fit inside the em square. There was, however, a hardcoded max
size in the distance field generator, so for very tall glyphs we
could potentially get a crash.

Compiler support for lambda functions and variadic templates is

what happens if the compiler doesn't support it.

This fixes the following Valgrind warning:
"Syscall param writev(vector[...]) points to uninitialised byte(s)
Uninitialised value was created by a stack allocation"
The xcb_send_event() requires all events to have 32 bytes.
It calls memcpy() on the passed in event. If the passed in
event is less than 32 bytes, memcpy() reaches into unrelated
memory. And as it turns out, this behavior is actually
described in the xcb_send_event function's documentation.
This patch adds a macro that declares an event for safe
usage with xcb_send_event.

C0 to DF take one continuation byte; E0 to EF take two.
It's invalid UTF-8 anyway, but at least this is what the test row meant:
overlong sequence with 3 bytes of what should have been two.
This updates the comment to match the character that we were actually
testing.

On POSIX compliant platforms, the default precision we apply to
preserving time stamps is seconds. However we can do better and use
utimensat() - if available - to increase the precision to nanoseconds.
The values are provided by statbuf's st_mtim. This is guarded for
compatibility with older systems, similar to commit
494ced1329.
