photoshop can eat a dick

ever tried to make a square in photoshop? it's not as easy as one might think. especially if you want to rotate it 45 degrees to the left, or make the outline thicker. i don't want to rasterize the image or dodge and burn or convert from rgb to cmyk - I JUST WANT TO MAKE A SQUARE THAT HAS THICK EDGES. WHY IS THAT SO HARD!?!?!?!
