INT scale_resolution_aspectratio = Scale_resolution_aspectratio_modes.

Description

Scale_resolution_aspectratio is a global variable used to choose between stretching a screen resized by scale_resolution to fill the screen or keeping his aspect ratio.

Example

Import "mod_video";
Import "mod_text";
Import "mod_key";
Import "mod_map";
Import "mod_proc";
Import "mod_screen";
