[SDL] sprite animation

[Lilith Calbridge]

I won't have a chance to pay full attention to the link until tomorrow. 
However, I have begun, for my own purposes of a presentation, developing
a class I call SCR_Object.  The pointer to the screen is kept there and
I used to run a routine that made sure that all screen objects had a
pointer to the screen.  Later I revised the pointer to be a static
object.  That essentially makes only one copy that can be seen by all
objects of the class.  Ditto for the background.  This prevents having
to pass the screen pointer to each object or relying on a specifically
named global screen pointer from having to be declared.  Now all I have
to do is to initialize one object (I usually reserve the name of SCRSys
for this purpose) as if it were the screen object and the pointer is
automatically available to each object in the class.
