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