pretty simple question, i know i can save a screenshot using file_for_screen but i need a resized screenshot, example, 180*180, now i did try resizing the screen before taking the shot, I assume i can use video_set/video_switch to change the res and then take the shot but honestly i'd rather avoid that.

OR is there someway to take the screenshot, resize it using bmap_blit for example and write it to harddisk in some other way? i'd still need to be able to read this back into the engine though
