Log message:
'IDirectFB::CreateSurface' can now be used to create surfaces using a
preallocated system memory buffer. Apps have to set 'DSDESC_PREALLOCATED'
and the appropriate fields in the surface description. The buffer won't be
freed if the surface gets destructed.
The application has to use the 'Lock' method even to access the system
memory buffer. Otherwise data coherency between system and video memory
isn't guaranteed.
