INT resolution = 0
This simulating of fractions in positions is useful for calculations or animations in need of a high precision in order to work properly. It causes the coordinates of all processes to be interpreted as being multiplied by the value of the local variable resolution, associated with that process. So when a process' graphic is displayed, it will appear as if the process' x and y values were divided by the value of resolution. A resolution of
0 is interpreted as if it were
The default value of resolution is 0, so set it to 1 if the correct value is needed.

Used in example: set_mode(), set_fps(), map_new(), drawing_map(), drawing_color(), draw_fcircle(), get_timer(), key(), let_me_alone(), map_unload(), advance(), resolution, graph, size, x, y, angle, exit_status
Here are a few screenshots with different resolutions to display the effect it can have.
The effect is clearly visible, so when you are moving processes with graphics around the screen, you might want to consider using a resolution of at least 10 in those processes.
