SDLx::App::loop is a simple event loop method which takes a reference to a hash
-of event handler subroutines. The keys of the hash must be SDL event types such
-as SDL_QUIT(), SDL_KEYDOWN(), and the like. When called, the event method recieves
-as its parameter the event object used in the loop.
Example:
- my $app = SDLx::App->new(

- height => 600,
