/* 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
