Make -axis shell argument not case sensitive

[Eliot Phillips]

Using the mirror command's -axis argument requires a capital letter X or Y and fails on x or y.

@sopak could we make options case insensitive? I was wondering if this was a quick fix that we could do for version 8.5 or deffer it to 9.0.

[Kamil Sopko]

for name of option it would be possible do it globally in new commands(TclCommand argument handling), but it is not good idea do it for options , for example name of output FILE and maybe name of object should be case sensitive.

if we need it , then we need it implemented it in specific commands.

[Juan Pablo Caram]

@sopak Correct, for option names only. Everything else stays case sensitive.

[Kamil Sopko]

but all option names are for now lowercase do we have to mess with this? same situation is with command names

[Juan Pablo Caram]

@sopak Oh, you are right. This issue is about the value, not the option name.

If you have implemented this command in the new way I can make the change to fix this issue.

I just tested this and the problem is not there. axis = kwa['axis'].upper() has been there for quite some time now.
