Naming Convention: document prefix "O"
Hi!
I was checking the LEDs footprints and found an "O" prefix in many items.
For example: LED_THT:LED_D3.0mm_Horizontal_O3.81mm_Z2.0mm
I think it is the horizontal dimension, but since I'd like to know where the prefix comes from. It would be a nice addition to the prefixes list (file) IMO.
Thanks in advance.
