Just some simple code that tests convolutions.

To compile:
  Run "make"
  You'll need the SDL and SDL_image devel packages installed.

Usage:
  ./convolve butterfinger.png
  
  e - edge detect
  m - emboss
  s - sharpen
  space - restore
  
I accidentally erased this, and recovered it using grep (on ext3 Linux).
