Make it use gdk_memory_texture_from_texture().
Also make gdk_memory_format_alpha() privately available so that we can
detect if an image contains an alpha channel.
Use our own loader to (de)serialiaze textures
to and from png and tiff.
We still fall back to gdk-pixbuf for handling all
the other image formats, and for pixbufs.
This is a neverending story. I was seeing problems in tests where
the nested mainloop was picking up unrelated timeouts.
Break down and make this async. This changes the ordering in which
the (de)serializers are registered. If this is causing issues, we
can introduce priorities or something else.
The argument is eventually passed to g_conv(), so it should
be the charset, not the mime/type. Without this change the
contentype converter will fail to convert UTF-8 strings to, say,
CP-1251 later on.
GdkContentFormatsBuilder is currently not introspectable, as it does not
have a GType. We can turn it into a boxed type, but we need to implement
memory management for it.
The current gdk_content_formats_builder_free() function returns a newly
constructed value, so we cannot use it as a GBoxedFreeFunc; additionally
copying a GdkContentFormatsBuilder contents would make it a bit odd, as
you could get multiple identical GdkContentFormats out of the copies.
A simple approach is to model the GdkContentFormatsBuilder API to follow
the GBytes one: use reference counting for memory management, and have
a function to release a reference, return a GdkContentFormats, and reset
the GdkContentFormatsBuilder state.
For language bindings, we can provide a get_formats() function that
returns the GdkContentFormats instance and resets the builder instance,
leaving the reference count untouched.
For C convenience we can keep gdk_content_formats_builder_free(), and
make it a wrapper around gdk_content_formats_builder_get_formats(), with
the guarantee that it'll free the builder instance regardless of its
current reference count.

We are using `path` unconditionally, but it can be conditionally filled.
To avoid inconsistent internal state, and a compiler warning, let's
assert that the variable is always set.
This is a GSList of GFile and we want it so we can operate with lists of
files and text/uri-list.
I chose GSList over GList because that's what the GtkFileChooser API
uses, too.
