I also have a question, I ask forgiveness for such English.
In general such a problem when using the scale inner, that for android, that like all good PC game goes to full screen, but not on the android image protrudes beyond the lower bar on the PC and in browsers that 16:9 monitor that 4:9, the image is generally beyond the scope of the monitor, scale outer works well only to 16:9 to 4:9, he does not cut the image on the right as it was before, and cuts off the bottom with concrete!
Translation of this innovation from our website:
Fullscreen in browsers, the option 'Scale' is replaced by 'Scale inner' and 'Scale outer'. 'Scale outer' does the same thing and did earlier. But the 'Scale inner' is a new version of the scale at which the game is "cut off" the edge of the screen, and do not stretch the game space, if the aspect ratio does not match. For example, it is useful to develop games 16:9, if the screen will have a 4:3 ratio, then the game will be "cut off" at the edges, and will be visible only to the central part.
