* Possiblilities:

* - manual colorkey drawing ( CK_METHOD_MANUALFILL )
* - set colorkey as window background ( CK_METHOD_BACKGROUND )
* - let Xv paint the colorkey ( CK_METHOD_AUTOPAINT )
* * Sources
* - use currently set colorkey ( CK_SRC_CUR )
* - use colorkey in vo_colorkey ( CK_SRC_USE )
* - use and set colorkey in vo_colorkey ( CK_SRC_SET )
*
* NOTE: If vo_colorkey has bits set after the first 3 low order bytes
* we don't draw anything as this means it was forced to off.
