/* Clipboard formats */
static struct list format_list = LIST_INIT(format_list);
/* There are two naming schemes involved and we want to have a mapping between
them. There are Win32 clipboard format names and there are Mac pasteboard
types.
The Win32 standard clipboard formats don't have names, but they are associated
with Mac pasteboard types through the following tables, which are used to
initialize the format_list. Where possible, the standard clipboard formats
are mapped to predefined pasteboard type UTIs. Otherwise, we create Wine-
specific types of the form "org.winehq.builtin.<format>", where <format> is
the name of the symbolic constant for the format minus "CF_" and lowercased.
E.g. CF_BITMAP -> org.winehq.builtin.bitmap.
Win32 clipboard formats which originate in a Windows program may be registered
with an arbitrary name. We construct a Mac pasteboard type from these by
prepending "org.winehq.registered." to the registered name.
Likewise, Mac pasteboard types which originate in other apps may have
arbitrary type strings. We ignore these.
Summary:
Win32 clipboard format names:
<none> standard clipboard format; maps via
format_list to either a predefined Mac UTI
or org.winehq.builtin.<format>.
<other> name registered within Win32 land; maps to
org.winehq.registered.<other>
Mac pasteboard type names:
org.winehq.builtin.<format ID> representation of Win32 standard clipboard
format for which there was no corresponding
predefined Mac UTI; maps via format_list
org.winehq.registered.<format name> representation of Win32 registered
clipboard format name; maps to <format name>
<other> Mac pasteboard type originating with system
or other apps; either maps via format_list
to a standard clipboard format or ignored

CF_TEXT, CF_OEMTEXT, and CF_UNICODETEXT in turn. We want to look up the natural
type for each of those IDs (e.g. CF_TEXT -> "org.winehq.builtin.text") and then see
if that type is present in the pasteboard. If it is, then we don't want to add the
format to the list yet because it would be out of order.
For example, if a Mac app put "public.utf8-plain-text" and "public.tiff" on the
pasteboard, then we want the Win32 clipboard formats to be CF_TEXT, CF_OEMTEXT, and
CF_UNICODETEXT, and CF_TIFF, in that order. All of the text formats belong before
CF_TIFF because the Mac app expressed that text was "better" than the TIFF. In
this case, as soon as we encounter "public.utf8-plain-text" we should add all of
the associated text format IDs.
But if a Wine process put "org.winehq.builtin.unicodetext",
"public.utf8-plain-text", "public.utf16-plain-text", and "public.tiff", then we
want the clipboard formats to be CF_UNICODETEXT, CF_TIFF, CF_TEXT, and CF_OEMTEXT,
in that order. The Windows program presumably added CF_UNICODETEXT and CF_TIFF.
We're synthesizing CF_TEXT and CF_OEMTEXT from CF_UNICODETEXT but we want them to
come after the non-synthesized CF_TIFF. In this case, we don't want to add the
text formats upon encountering "public.utf8-plain-text",
We tell the two cases apart by seeing that one of the natural types for the text
formats (i.e. "org.winehq.builtin.unicodetext") is present on the pasteboard.
