Maybe someone that looked at a clock or compass? TRBL matches 12o'clock, 3o'clock, 6o'clock, 9o'clock. It also matches N E S W going around the circle I agree

Maybe someone that looked at a clock or compass? TRBL matches 12o'clock, 3o'clock, 6o'clock, 9o'clock. It also matches N E S W going around the circle I agree that I'm more familiar with left being first but then should it be LRTB or LTRB. LRTB is common to say. But many APIs take x,y first which would arguably be LT. Basically I think you could justify almost any order
