Say one lays out a one-sided board with the letter "G" in the lower

Then make four gerbers: X asis, Y asis; X mirrored, Y asis; X asis, Y

That is to say, you *TELL* the EDA to do those operations, eXplicitly!

Please tell me the following:
1) What does -->your<-- EDA generate - ie: what did it *really* do?
2) What is the *standard* for the fab shops, and exactly why?

All Gerbers that I send to a board shop are as viewed from the
component side of the board - even those for the solder side of the
board. Any lettering I put on the board will be readable on the
finished board, so lettering on the solder side is mirrored in the
design program (Protel).
