[AD] set_clip and set_clip_rect

[Chris <kcat@xxxxxxxxxx>]

I can't seem to find any messages in my inbox explaining this, so 
perhaps someone here can enlighten me.

What was the purpose of creating set_clip_rect and deprecating set_clip? 
 Though both take exactly the same arguments, and as far as I can see, 
do exactly the same thing (set the main clip rectangle). Perhaps there's 
some deep reason I can't see, but having to do something like this to 
get rid of a warning is annoying:

#if ((ALLEGRO_VERSION*10000 + ALLEGRO_SUB_VERSION*100 + 
ALLEGRO_WIP_VERSION) >= (4*10000 + 1*100 + 14))
	set_clip_rect(stream->bitmap, 0, 0, stream->w-1, stream->h-1);
#else
	set_clip(stream->bitmap, 0, 0, stream->w-1, stream->h-1);
#endif

As you can see, both commands are exactly the same, except one needs a 
_rect suffix. It was also a bit annoying to have to figure out that #if 
statement to check for a proper Allegro version number..
