GUICtrlSetImage needs wrong icon index to show needed icon

[Pumbaa]

GUICtrlSetImage needs wrong icon index to show needed icon.
In 3.2.X.X (don't remember exact version) I used such code

$About = GUICtrlCreateButton ("", 184, 5, 21, 21, $BS_ICON)
GUICtrlSetImage (-1, "shell32.dll", 172, 0)

But after installing 3.3.0.0 I've got wrong icon & found that now icon index became +110 - so:

#include <ButtonConstants.au3>

$About = GUICtrlCreateButton ("", 184, 5, 21, 21, $BS_ICON)
GUICtrlSetImage (-1, "shell32.dll", 282, 0)

After small exploration I've found that about first 50 icons are ok, but further indexes indent with growing delta (delta is not constantly 110).

Just reread the doc as negative index have been introduce to differentiate name and index reference
