Comment (by criezy):

 Let's put aside the GUI menu size for now and focus on the window size.

 I am not sure what `window being abnormaly huge` means, but I did some
 additional tests and I am getting the expected window size with both
 Normal and HQ scalers.

 You can run scummvm with `-d 3` to get output on the window size.

 On a Retina laptop I cannot test 3x scalers as the screen is too small,
 but with 2x scalers and COMI I get the following:
 {{{
 Normal 2x: Setting 1280 x 960 -> 1280 x 960 -- 1
 HQ 2x: Setting 1280 x 960 -> 1280 x 960 -- 1
 }}}

 That is the expected size, and it matches what I get with ScummVM 2.2.0.

 Note: with Surface SDL mode, since HiDPI is not enabled, we are running in
 compatibility mode and the OS applies a 2x scaler on its own. On the
 ScummVM side we see things as if the screen had half the DPI that it
 really has. So the window is actually 2560x1920.

 On my non-retina iMac, I can test the 3x scalers and I also get the
 expected result:
 {{{
 Normal 3x: Setting 1920 x 1440 -> 1920 x 1440 -- 1
 HQ 3x: Setting 1920 x 1440 -> 1920 x 1440 -- 1
 }}}

 In all cases I am getting the expected window size, and it matches the
 size I have with ScummVM 2.2.0.
