Compatibility: VGA
Expects: AX    1c02H
CX    type(s) of video-state info to restore (see below)
ES:BX address of buffer containing video-state info
Returns: AL    1cH (if this fn is supported)
Info: This restores the VGA video system to its state at the time when
it was saved via INT 10H 1c01H.

CX is a set of bit-flags indicating what types of video-state
information you need to restore:
1 1
 5 4    7 6 5 4 3 2 1 0 
 0 0    0 0 0 0 0 c d h 
                         bit mask
        0: 01H  video hardware state info
        1: 02H  video BIOS data area info
        2: 04H  DAC state and color registers

ES:BX Be sure that the data at this address contains valid information
as saved via INT 10H 1c01H (with CX having the same value!).

The layout of the video-state information is not documented.

Notes: This is very handy for task-switching software such as the DOS
Shell and can be useful in systems that switch in-and-out of
graphics modes.
