  23  * NOTES:
  24  *    This file contains the X specific implementation for the windows
  25  *    Clipboard API.
  26  *
  27  *    Wine's internal clipboard is exposed to external apps via the X
  28  *    selection mechanism.
  29  *    Currently the driver asserts ownership via two selection atoms:
  30  *    1. PRIMARY(XA_PRIMARY)
  31  *    2. CLIPBOARD
  32  *
  33  *    In our implementation, the CLIPBOARD selection takes precedence over PRIMARY,
  34  *    i.e. if a CLIPBOARD selection is available, it is used instead of PRIMARY.
  35  *    When Wine takes ownership of the clipboard, it takes ownership of BOTH selections.
  36  *    While giving up selection ownership, if the CLIPBOARD selection is lost,
  37  *    it will lose both PRIMARY and CLIPBOARD and empty the clipboard.
  38  *    However if only PRIMARY is lost, it will continue to hold the CLIPBOARD selection
  39  *    (leaving the clipboard cache content unaffected).
  40  *
  41  *      Every format exposed via a windows clipboard format is also exposed through
  42  *    a corresponding X selection target. A selection target atom is synthesized
  43  *    whenever a new Windows clipboard format is registered via RegisterClipboardFormat,
  44  *    or when a built-in format is used for the first time.
  45  *    Windows native format are exposed by prefixing the format name with "<WCF>"
  46  *    This allows us to uniquely identify windows native formats exposed by other
  47  *    running WINE apps.
  48  *
  49  *      In order to allow external applications to query WINE for supported formats,
  50  *    we respond to the "TARGETS" selection target. (See EVENT_SelectionRequest
  51  *    for implementation) We use the same mechanism to query external clients for
  52  *    availability of a particular format, by caching the list of available targets
  53  *    by using the clipboard cache's "delayed render" mechanism. If a selection client
  54  *    does not support the "TARGETS" selection target, we actually attempt to retrieve
  55  *    the format requested as a fallback mechanism.
  56  *
  57  *      Certain Windows native formats are automatically converted to X native formats
  58  *    and vice versa. If a native format is available in the selection, it takes
  59  *    precedence, in order to avoid unnecessary conversions.
  60  *
  61  * FIXME: global format list needs a critical section
