This is a minor but necessary update.  Compatible with GMS2.3.7.403 and later.  The latest version of the scripts are backwards compatible and they won't break your projects. Just remove the old version before importing the new one.

Now all arguments except the _design_value in the set_resolution are optional meaning that:

set_resolution(640);

is the same as:

set_resolution(640, false, false, false);

The set_gui_size script has been impoved. Both arguments are optional now. If both arguments omitted then the GUI layers size will be the same as the game's resolution.  If either argument ommited then it will be calculated to fit the current aspect ratio of the game's resolution.
