Gerbview did not handle redefinition of variable like $3 = $3 / 2
This redefinition is sometimes found in Gerber files.
This is a long standing issue now fixed.
Fixes#7222https://gitlab.com/kicad/code/kicad/issues/7222
In Gerber files the char 'X' is used as separator.
But when reading parameter values, the sequence "0xnnn" is a number in hexadecimal format, and the 'X' char is not seen as separator by usual strtod or strtol C functions.
This is now fixed.
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
* Correct all user strings and comments for the correct capitalization of
application names according to JP. They are KiCad, Pcbnew, CvPcb,
Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
