99 /* There are two naming schemes involved and we want to have a mapping between
100 them. There are Win32 clipboard format names and there are Mac pasteboard
101 types.
102
103 The Win32 standard clipboard formats don't have names, but they are associated
104 with Mac pasteboard types through the following tables, which are used to
105 initialize the format_list. Where possible, the standard clipboard formats
106 are mapped to predefined pasteboard type UTIs. Otherwise, we create Wine-
107 specific types of the form "org.winehq.builtin.<format>", where <format> is
108 the name of the symbolic constant for the format minus "CF_" and lowercased.
109 E.g. CF_BITMAP -> org.winehq.builtin.bitmap.
110
111 Win32 clipboard formats which originate in a Windows program may be registered
112 with an arbitrary name. We construct a Mac pasteboard type from these by
113 prepending "org.winehq.registered." to the registered name.
114
115 Likewise, Mac pasteboard types which originate in other apps may have
116 arbitrary type strings. We ignore these.
117
118 Summary:
119 Win32 clipboard format names:
120 <none> standard clipboard format; maps via
121 format_list to either a predefined Mac UTI
122 or org.winehq.builtin.<format>.
123 <other> name registered within Win32 land; maps to
124 org.winehq.registered.<other>
125 Mac pasteboard type names:
126 org.winehq.builtin.<format ID> representation of Win32 standard clipboard
127 format for which there was no corresponding
128 predefined Mac UTI; maps via format_list
129 org.winehq.registered.<format name> representation of Win32 registered
130 clipboard format name; maps to <format name>
131 <other> Mac pasteboard type originating with system
132 or other apps; either maps via format_list
133 to a standard clipboard format or ignored
