The places view has questionable code for handling
'destroy', which seems to trigger use-after-free in
some cases. Clean this up a bit by acknowledging the
cancellation fully, rather than relying on the
destroyed flag.
When we are rendering a texture node to an offscreen,
and we have a clip, we must force the offscreen rendering.
Otherwise, the code will notice: Hey, it already is a texture
node, so no need to render it to a texture again. But when
clipping is involved, that is exactly what we want to do.
Testcase included.

- while the case of a single half tiled window casting shadow is valid,
the main use case for half tiled windows is when they have a neighbor.
The :backdrop should be enough of a focus indicator and we avoid shadow
casting on neighbors that are on the same Z level.
These shadows cause a significant draw performance drop for maximized
windows. Disabling them increases the chances we can have faster scroll
performance of text.
There is some risk here for systems where they have a dock and you expect
the shadow to draw beneath that dock for transparency reasons.
We do not need to translate this on the CPU when we can instead push it
to the GPU in the same format and allow it to swizzle.
This fixes a huge number of memory allocations found while uploading the
GTK animation in widget-factory.
There isn't any state to modify in the type so we can use const here.
Doing so allows some of the renderer code to use const across a
number of functions so that repeated calls are elided if inlined.
These do not do modify anything so they can be marked as pure to
potentially ellide calls. Since they do dereference, I do not believe
we can make them const although that is unclear since we could technically
just return a pointer + offset. Therefore it *might* be possible to also
make these G_GNUC_CONST.
This also removes the return if fail macros from these as a good portion
of them didn't have them anyway. I think it's fair to say that access to
these incorrectly is a programmer error.
It significantly reduces the amount of code generated into generally a
movss,ret.
Just compiling these out means you have to write code slightly differently
so that you don't end up with "if ();" afterwards.
This adds a "do {} while (0)" so that we're still semantically a statement
but will also compile out.
My reading of the code is that gdk_drop_new() is not
consuming the content formats it is given, so the caller
must not pass a new reference.
Needs testing on Windows.
Whenever we communicate targets, we need to the union, otherwise
we don't tell the other side about our serialization. This makes
drops of images from gtk4-icon-browser to gimp and libreoffice
succeed in transferring data.

When creating the output stream for a drop, we must
pass the mimetypes we support, otherwise the picking
of the right handler does not work.
Fixes: #3652
