Deleting shader!

[ghost]

When you load the vertex and fragment shader you try to delete them but they never(Until you close the window) are going to be deleted because they need to be detached first from the program.

This is true, but should be an easy fix. Before this line, simply append:

glDetachShader(program, vertex);
glDetachShader(program, fragment);

This must be done since deleting a shader doesn't automatically detach it from the program (as described here).

I could create a pull request if it would be appreciated.
