Apply offset by 1px for our provided fonts

[dbz400]

Trying to detect original PSP fonts here (only jpn0.pgf ) and apply offset by 1px for non original one which is the one we provided in our package

Partially fix #2675

Can you do the reverse check instead? That is, check for the size (or hash) of our font file instead. That way we won't apply the offset if someone replaces them with their own font of some sort.

Why not do a SHA-1 hash instead of checking for size? Someone could easily spoof the same size file (not that it's likely, but it's much easier to spoof a blank file/pad a file then it is to fake a SHA-1).

This is obviously very hacky... not sure if we're concerned about spoofing, though?

Spoofing sounds like a pretty remote concern.

Not a big fan of the hackiness of this either, but checking for and "fixing" our own font files is the reasonable way, if we're going to do it ....

[dbz400]

It is bit hacky anyway, at least useful for this time being as fixing our own font files may not be happened so soon .
