19	/* The driver operates in 3 modes:
20	* 1) BASE : Driver does not report to host about any operations.
21	* All Drv* are immediately routed to Eng*.
22	* 2) VBVA : Driver reports dirty rectangles to host.
23	* 3) VBVA + VRDP : Driver also creates orders pipeline from which VRDP
24	* can reconstruct all drawing operations, including
25	* bitmap updates.
26	*
27	* These modes affect only VBoxDispDrv* functions in this file.
28	*
29	* VBVA mode is enabled by a registry key for the miniport driver
30	* (as it is implemented now).
31	*
32	* VRDP mode is enabled when a VRDP client connects and VBVA is enabled.
33	* The host sets a bit flag in VBVAMemory when VRDP client is connected.
34	*
35	* The VRDP mode pipeline consists of 3 types of commands:
36	*
37	* 1) RDP orders: BitBlt, RectFill, Text.
38	* These are the simplest ones.
39	*
40	* 2) Caching: Bitmap, glyph, brush.
41	* The driver maintains a bitmap (or other objects) cache.
42	* All source bitmaps are cached. The driver verifies
43	* iUniq and also computes CRC for these bitmaps
44	* for searching. The driver will use SURFOBJ::dhsurf
45	* field to save a pointer to in driver structure, even
46	* for Engine managed bitmaps (hope that will work).
47	*
48	*
49	* 3) Bitmap updates, when given draw operation can not be done
50	* using orders.
