============ Function 21, subfunction 13, subsubfunction 1 ===========
======== Initialize + get information on the driver vmode.mdr. =======
======================================================================
Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 1 - number of the driver function
* edx = pointer to 512-bytes buffer
Returned value:
* if driver is not loaded
(never happens in the current implementation):
* eax = -1
* ebx, ecx destroyed
* if driver is loaded:
* eax = 'MDAZ' (in fasm style, that is 'M' - low byte, 'Z' - high)
- signature
* ebx = current frequency of the scanning (in Hz)
* ecx destroyed
* buffer pointed to by edx is filled
Format of the buffer:
* +0: 32*byte: driver name, "Trans VideoDriver"
(without quotes, supplemented by spaces)
* +32 = +0x20: dword: driver version (version x.y is encoded as
y*65536+x), for the current implementation is 1 (1.0)
* +36 = +0x24: 7*dword: reserved (0 in the current implementation)
* +64 = +0x40: 32*word: list of supported videomodes (each word
is number of a videomode, after list itself there are zeroes)
* +128 = +0x80: 32*(5*word): list of supported frequences of the
scannings for videomodes: for each videomode listed in the
previous field up to 5 supported frequences are given
(unused positions contain zeroes)
Remarks:
* Function initializes the driver (if it is not initialized yet)
and must be called first, before others (otherwise they will do
nothing and return -1).
* The current implementation supports only one frequency
of the scanning on videomode.

============ Function 21, subfunction 13, subsubfunction 2 ===========
================ Get information on current videomode. ===============

Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 2 - number of the driver function
Returned value:
* eax = -1 - driver is not loaded or not initialized;
ebx,ecx are destroyed
* eax = [width]*65536 + [height]
* ebx = frequency of the vertical scanning (in Hz)
* ecx = number of current videomode
Remarks:
* Driver must be initialized by call to
driver function 1.
* If only screen sizes are required, it is more expedient to use
function 14 taking into account that it
returns sizes on 1 less.

Parameters:

* edx = [scanning frequency]*65536 + [videomode number]
Returned value:
* eax = -1 - driver is not loaded, not initialized or
an error has occured

Remarks:
* Driver must be initialized by driver function 1.
* The videomode number and frequency must be in the table

* ecx = 5 - number of the driver function
* edx = 0/1 - decrease/increase horizontal size on 1 position
* edx = 2/3 - is not supported in the current implementation;
is planned as decrease/increase vertical size on 1 position
Returned value:
* eax = -1 - driver is not loaded or not initialized
* eax = 0 - success

Remarks:
* Driver must be initialized by call to driver function 1.

Remarks:
* The format of the table with tracks information is the same as
