Re: Compose rectangles within another rectangle

This is called bin packing.  You'll find much research on it, and even 
this very question has been answered a few times in the archives of this 
list.  To save you a few seconds, some folks suggest an approach similar 
to Tetris.  Personally, I sort rectangles by the longest axis and pack 
from longer to shorter, minimizing the distance to the origin of the 
texture sheet when placing them.  That tends to work pretty well.  If 
you can do it offline, slowly shuffling the order you submit the 
rectangles a little bit can get you some good gains over the simple 
sorting method, but it all depends on how much effort you want to put 
into it.

Best of luck,
