Allow pre-Donut apps to use indirect Buffers in GL11 Pointer methods.
Apps targeting Donut and newer will throw an exception.
We use a heuristic to determine whether an app is pre-Donut or not:
We take the address space's __progname, and use that as the application's
package name. For simple applications this is correct.
