/* Suppose type is "public.utf8-plain-text". format->format_id will be each of
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.
"found" indicates that. */
