Color mixer example

Simple example to show some color manipulation functions.

Compilation

Easiest way to get this example running is to go to examples directory in package root, and run:

$ ./build.sh color_mix

build.sh script compiles Ano script to C, copies source files in place and pops up instructions what to do next. Follow them. Check also examples/README for more info.
