Hi all,
I have several objects moving and they must refresh their position on
screen on synchronous mode.
Is there is any way to make something lika a display buffer?
I mean, to perform the positioning of objects without changing what you
see on the display, and finally, refresh the display when everything is
ready for viewing.
