The `GdkDmabufFormats` struct provides information about supported DMA buffer formats.
You can query whether a given format is supported with [method@Gdk.DmabufFormats.contains] and you can iterate over the list of all
supported formats with [method@Gdk.DmabufFormats.get_n_formats] and [method@Gdk.DmabufFormats.get_format].
The list of supported formats is sorted by preference, with the best formats coming first.
The list may contains (format, modifier) pairs where the modifier is `DMA_FORMAT_MOD_INVALID`, indicating that **_implicit modifiers_**
may be used with this format.
See [class@Gdk.DmabufTextureBuilder] for more information about DMA buffers.
