+Description: Handle source pictures (those without a Drawable surface) gracefully.
+Author: Mihai Moldovan <ionic@ionic.de>
+Abstract:
+ This is basically a merge of the most current xorg-server (1.17.1) code into
+ nx-X11.
+ .
+ It makes sure that for source pictures, which do not have a drawable surface,
+ a filter is selected that is supported on the "main" and all other screens.
+ Alternatively, if the requested filter is not available on all screens and
+ the picture is a source picture, this function fails gracefully.
+ .
+ Additionally, the ChangePictureFilter hook is now called for non-source
+ pictures.
+ .
+ This also needs an implementation in mipict.{c,h}. The default hook does
+ nothing and returns a success value.
