f78b12e570284aa8291f4ca1add24937fd107403vboxsync DIX will fill everything out in the context except the driver_priv.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync The port_priv holds the private data specified for the port when
f78b12e570284aa8291f4ca1add24937fd107403vboxsync Xv was initialized by the driver.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync The driver may store whatever it wants in driver_priv and edit
f78b12e570284aa8291f4ca1add24937fd107403vboxsync the width, height and flags. If the driver wants to return something
f78b12e570284aa8291f4ca1add24937fd107403vboxsync to the client it can allocate space in priv and specify the number
f78b12e570284aa8291f4ca1add24937fd107403vboxsync of 32 bit words in num_priv. This must be dynamically allocated
f78b12e570284aa8291f4ca1add24937fd107403vboxsync space because DIX will free it after it passes it to the client.

f78b12e570284aa8291f4ca1add24937fd107403vboxsync DIX will fill everything out in the surface except the driver_priv.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync The driver may store whatever it wants in driver_priv. The driver
f78b12e570284aa8291f4ca1add24937fd107403vboxsync may pass data back to the client in the same manner as the

f78b12e570284aa8291f4ca1add24937fd107403vboxsync DIX will fill everything out in the subpicture except the driver_priv,
f78b12e570284aa8291f4ca1add24937fd107403vboxsync num_palette_entries, entry_bytes and component_order. The driver may
f78b12e570284aa8291f4ca1add24937fd107403vboxsync store whatever it wants in driver_priv and edit the width and height.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync If it is a paletted subpicture the driver needs to fill out the
f78b12e570284aa8291f4ca1add24937fd107403vboxsync num_palette_entries, entry_bytes and component_order. These are
f78b12e570284aa8291f4ca1add24937fd107403vboxsync not communicated to the client until the time the surface is
