I really don't know what to call this. Anyway... uh.. features!

• displays frame rate in top left corner
• displays current cursor coordinates
• marks cursor position when clicked
• red lines to look cool

And all that is only available to you once you click the right mouse button. So you can switch between modes quickly!

I guess this can help you if you're placing objects about your scene, and you really want to know the position of your cursor.

Enjoy!
