 -Notes-
 * The renderer code is based on the gl like engine. It's not using the sprite engine.
+* The hardware renderer is using the parts of the libgl2d abstraction library that can be found at:
+    http://rel.phatcode.net/junk.php?id=117
+  Used with the author's permission.
 * The port is very basic and incomplete:
-  - SDL currently has to be compiled for either framebuffer mode or render mode.
+  - SDL currently has to be compiled for either framebuffer mode or renderer mode.
      See USE_HW_RENDERER in Makefile.ds.
   - some optional renderer functions are not implemented.
+  - no sound
 
 -Limitations-
 * in hardware renderer mode, don't load too many textures. The internal format is
   2 bytes per pixel. And there is only 256KB reserved for the textures. For instance,
   testscale won't display sample.bmp, unless it's resized to a smaller picture.
 * the screen size is 256 x 384. Anything else won't work.
-* there is no 8 bits/pixel mode because SDL 1.3 doesn't support palettes.
+* there is no 8 bits/pixel mode because SDL 2.0 doesn't support palettes.
