 - More image formats:
   - DPX & CIN
   - EXR (using the OpenEXR libraries)
-  - TIFF (using libtiff)
 - Support for loading/processing images in tiles.
 
+- Split the current image abstraction into two parts:
+  - Texture (which describes data in texture memory on the GPU).
+  - Image (which describes a grid of pixels in RAM).

 - Code to find out where a ray hits a scene.
 
 - Support for mouse gestures.

+- Divide the source code up into subdirectories.
+  - Maybe into sub-namespaces as well?

+- Some camera classes:

 - A *very* simple renderer abstraction.
+- Helper functions for dealing with OpenGL shaders.
 - An example program which draws a lit teapot.
 - An example program which loads and displays a model file.

 TODO
 ====
 
-- Make the Camera class more suitable for subclassing.
-- Add support for orthographic cameras.
-- Add a proper arcball implementation.
-
 - Make the current format-specific image loading functions public.
 - Make it possible to register additional image loaders without changing the VGL code.

 - Make sure we're only exporting the public symbols from the library.
 
+- Get rid of the BaseCamera class (or gut it, so that it's better for subclassing).
