 About the iPhone OS Demo Applications
 ==============================================================================
 
-Demos.xcodeproj contains several targets for iPhone oriented SDL demos.  These demos are written strictly using SDL 2.0 calls.  All the demos except for Fireworks (which requires OpenGL ES) should work on platforms other than iPhone OS, though you'll need to write your own compile script.  To run them on your favorite platform, you may wish to set the macros SCREEN_WIDTH and SCREEN_HEIGHT, located in common.h.

 Common files:
 
-	common.c and common.h contain code common to all demo applications.  This includes macros about the screen dimensions (in pixels), simple error handling, and functions for generating random numbers.

 Rectangles (rectangles.c):
 
-	Draws randomly sized and colored rectangles all over the screen by using SDL_RenderFill.  This is the simplest of all the demos.
