+  Sets the specified resolution. Can be up to the maximum supported resolution. If a larger or invalid resolution is provided it will throw an error. Returns `true` if the resolution was changed (may return `false` if an attempt was made to set it to the same value it was set before), `false` otherwise.
 - `getViewport(): number, number`

-  Set the current viewport resolution.
+  Set the current viewport resolution. Returns `true` if it was changed (may return `false` if an attempt was made to set it to the same value it was set before), `false` otherwise. This makes it look like screen resolution is lower, but the actual resolution stays the same. Characters outside top-left corner of specified size are just hidden, and are intended for rendering or storing things off-screen and copying them to the visible area when needed. Changing resolution will change viewport to whole screen.
 - <del>`getSize(): number, number`
   Gets the size in blocks of the screen the graphics card is bound to. For simple screens and robots this will be one by one.</del> Deprecated, use `screen.getAspectRatio()` instead.
