* GNU Make.
* A GPU capable of running GLSL fragment shaders,
process floating-point textures, and a few other things. If your machine
- is less than five years old _and you have the appropriate drivers_
- (don't complain to me if it doesn't work with Nouveau, please),
+ is less than five years old _and you have the appropriate drivers_,
you're home free.
* The [Eigen 3] and [Google Test] libraries. (The library itself
depends only on the former, but you probably want to run the unit tests.)
+* The [GLEW] library, for dealing with OpenGL extensions on various
+ platforms.
Movit has been tested with Intel GPUs with the Mesa drivers
(you'll probably need at least Mesa 8.0), Radeon 3850 and GeForce GTX 550
===============================================
Blur, diffusion, glow, lift/gamma/gain (color correction), mirror,
-mix (add two inputs), scale (bilinear and Lanczos), sharpen
-(both by unsharp mask and by Wiener filters), saturation (or desaturation),
-vignette, and white balance.

Yes, that's a short list. But they all look great, are fast and don't give
you any nasty surprises. (I'd love to include denoise, deinterlace and
