Для интерпретации данных графического экрана требуется знание
некоторых параметров, которые возвращаются этой функцией.
Замечания:
* Параметры графики очень редко меняются при работе системы,
а именно, только в случаях, когда пользователь работает
с программой VRR.
* Параметры графики очень редко меняются при работе системы.
* При изменении видеорежима система перерисовывает все окна
(событие с кодом 1) и перерисовывает фон (событие 5).

To interpret the data of graphics screen program needs to know
some parameters, returning by this function.
Remarks:
* Graphics parameters changes very seldom at work,
namely, only in cases, when user works with the application VRR.
* Graphics parameters changes very seldom at work.
* At videomode change the system redraws all windows (event
with code 1) and redraws the background (event 5).
Same events occur in other cases too, which meet much more often,
