Did you mean 320×240?
360x270 wouldn't be possible with VGA.
4:3 pixel aspect ratios of mode X-like VGA modes
256×256: 1.0 (Stretched) 320×200: 1.6 (Mode 13h - slightly squished) 320×224: 1.428.. (Imperceptibly squished) 320×240: 1.333.. (Square) 320×350: 0.914.. (Stretched) 320×400: 0.8 (Stretched) 320×480: 0.666.. (Extremely stretched) 360×200: 1.8 (Very squished) 360×240: 1.5 (Imperceptibly squished except when drawing circles) (360×270 is impossible) 360×350: 1.029.. (Slightly stretched) 360×400: 0.9 (Stretched) 360×480: 0.75 (Extremely stretched) 400×300: 1.333.. (Square)
But it was 320x240 that had the square pixels.
