I'm in favor for a several reasons, one of them selfish :)

1) I've never used them, so it won't affect me (and that's not the 
selfish reason)

2) From a brief look at the functions, it sounds like an improvement in 
clarity, and possibly speed.

3) There's a good chance the functions will get better documented as a 
result, so people that didn't take the time to figure them out before, 
may get a benefit from them with this change... (hint, hint)  :)

4) If I get a nice scrolling bitmap example code, I'll be really happy, 
and withdraw my request for adding back the old Win32::GUI::MDI object. 
  (Yep, this is the selfish one, but slightly altruistic as well.)
