65df740a33 Correct SAA5050 ROM encoding
The character at 6/0 is emdash (5 pixels long), not endash (4 pixels
long).

aef13db78d Encodings for the remaining chips in rom.ps
I have some disagreements with the SAA5057 image that I found, but I
agree with the datasheet which is good enough for now.

036d2b3e15 New question mark for SAA5051 and SAA5052
It's a different shape from the one used by the other chips.  Checked
against the 1982 datasheet and a real SAA5051.

20e3456c3e Add "rom.ps" for generating MAME-style font ROM images
This could be used to provide images for MAME to use, but it's also
useful for comparing against images from other sources to spot errors.
