Modified files:
src/core : fbdev.c layers.c layers.h
Log message:
Added 'dfb_layers_hook_primary()' that allows drivers to wrap/extend/replace
the implementation of the primary layer. The driver can provide an alternative
implementation for one or more functions of the primary layer and gets the
original content of the function table to use existing functionality.
The alternation grade ranges from "i-can-set-the-opacity" to "what-is-fbdev".
It's now allowed to return zero in LayerDataSize(),
primaryLayerDataSize() does that now, it had pseudo data before.
