Perturbatio

the $FF000000 represents an AARRGGBB integer, the $FF portion being full opacity, doing a bitwise AND between it and the pixel we are checking will return a boolean true when the pixel has full opacity

Technically, that line could be changed to:

Return pix & $FF000000

in fact a further optimisation could be:

Method HitTest:Int(hitX:Float, hitY:Float)
	Return ReadPixel(_pixmap, hitX, hitY) & $FF000000
End Method

And if further optimised could be something like:

If ReadPixel(_pixmap, MouseX()-X, MouseY()-Y) & $FF000000 Then
	If (onClick <> Null) Then
		onClick()
	EndIf
EndIf

I'm not sure I'm explaining it as well as I could, my brain understands it better than I do.
