22	/* The driver operates in 3 modes:
23	* 1) BASE : Driver does not report to host about any operations.
24	* All Drv* are immediately routed to Eng*.
25	* 2) VBVA : Driver reports dirty rectangles to host.
26	* 3) VBVA + VRDP : Driver also creates orders pipeline from which VRDP
27	* can reconstruct all drawing operations, including
28	* bitmap updates.
29	*
30	* These modes affect only Drv* functions in this file.
31	*
32	* VBVA mode is enabled by a registry key for the miniport driver
33	* (as it is implemented now).
34	*
35	* VRDP mode is enabled when a VRDP client connects and VBVA is enabled.
36	* The host sets a bit flag in VBVAMemory when VRDP client is connected.
37	*
38	* The VRDP mode pipeline consists of 3 types of commands:
39	*
40	* 1) RDP orders: BitBlt, RectFill, Text.
41	* These are the simpliest ones.
42	*
43	* 2) Caching: Bitmap, glyph, brush.
44	* The driver maintains a bitmap (or other objects) cache.
45	* All source bitmaps are cached. The driver verifies
46	* iUniq and also computes CRC for these bitmaps
47	* for searching. The driver will use SURFOBJ::dhsurf
48	* field to save a pointer to in driver structure, even
49	* for Engine managed bitmaps (hope that will work).
50	*
51	*
52	* 3) Bitmap updates, when given draw operation can not be done
53	* using orders.
