Image convert example

Example to read one image in and write another out. You need to provide image_input.tga as an input image and place it in current working directory.

Compilation

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

$ ./build.sh image_convert

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.
