What you are saying is that you want to have a directbuffer before
you have set the mode? This is not possible.

Directbuffers are always the size required by the video mode,
you don't set/get the directbuffer's size. The directbuffer doesn't
take any actual space, only the space required by the struct -- the
actual window is either a MMIO mapping into VRAM, or it is a RAM
backbuffer that is used by the visual whether or not you use it as
a directbuffer, or it is simply not available on that target.

The ResourceRelease is just there to inform other threads that
you are currently accessing using the DirectBuffer, so they
do not start any accelerator commands. It doesn'y alloc/dealloc anything.
