Yes, it is, same as Gimp, and same as in most graphics applications, and graphics APIs. A side effect is that the trigonometric direction is clockwise...
An explanation is that in the real world, the fixed point of a visual element is very often is top-left corner, so when you resize it it doesn't change the coordinates of things in contains if they are relative to that corner. Using the bottom left corner would require to adjust objects coordinates to keep them as the same place when you enlarge the visual element.
