I will include this in next version patch. Also it looks like Windows
window initialization don't work properly. Almost all fullscreen
examples are screwd (before applying the patch).
Right now I will not commit anything. More test should be done before
Allegro will fit in multi-monitor policy on Windows.

This to accomodate situations where that information is not readily available. It's probably also slightly more error-safe, since it may not be valid to assume that between Allegro initialising the default value of the current display and the user creating the display that the main display number we retrieved before is still valid.

Of course, it may need to do that internally (eg, on Windows).
