[AD] generic game loop

[Jon Rafkind <workmin@xxxxxxxxxx>]

I was wondering if Allegro could benefit from having a generic game loop 
function that users can use to run their games. I hope its not to 
ridiculous..

Something like
int game_loop( int (*logic)( void * data ), int (*draw)( void * data), 
int time, void * data );

Where logic is a function pointer to the function that performs all the 
game logic, draw is a function that draws everything, time is how much 
time to wait between loops and data is passed to logic() and draw() when 
they are called.

I havent attached game_loop because I didnt want to spend the energy to 
formalize the function unless people cared although it would just be 
some of my own code with minor modifications anyway, but it would look 
something like:
while ( !quit ){
    int dodraw = 0;
   while ( counter < 0 )
      counter--;
      logic( data );
      dodraw = 1;
   }
   if ( dodraw ) draw( data );
}

The reason I think this could be in Allegro is a) the question of how to 
do correct timing loops comes up again and again b) im sure many users 
get the timing loop suboptimal even if they know what it is and c) it 
reminds them of the "correct" way to structure games by seperating 
drawing and logic code.

I can see a critiscm be "This is a basic part of games that people 
should know how to do and doesnt belong in a graphics library." but this 
is exactly the point, its so common( or should be ) that it might as 
well go in a game library, which Allegro is supposed to be.

Just an idea, I wont be to upset if it gets shot down.
