Transparent background in OpenGL

One of the things I plan to improve in future versions of RW icon editor is the 3D object to image conversion. Right now, I am only using OpenGL while editing. In the future, it may also be used for the final conversion from a 3D object to an image or an icon. Icons typically have a transparent background, so let me say a few words about what I had to do to perform offscreen rendering in OpenGL with transparent background.
