Equilateral Triangles

[Richmond]

I am importing equilateral triangle images, which are, obviously, 
contained in square PNG image files.

When I either ROTATE or SET THE ANGLE of these images by 120 degrees 
they rotate, but the also jump around the screen because
there is NO way one can centre an equilateral triangle in a square.

Of course . . . if there was a way to readily import Vector images into 
LiveCode . . .

And before you say it: converting the PNG images using 'convert' in 
Linux to make EPS files yields files, that while being
openable in InkScape cannot be imported by Alejandro El Tejada's stacks.
