Palette cli

[justinlaughlin]

• Adds the option to specify a palette using CLI arg -pname or --palette-name
• Adds option to specify an external palette file and/or palette name to use in glvis "scripts" and streams
• Internally, use PaletteState.SetFallbackIndex() over PaletteState.SetIndex() to specify a fallback index if the default is not specified (implementation would have been more invasive via PaletteState so it is done through the global BasePalettes)

How about script and stream commands. Could you add them too? 😉 If you branch this from #335 , it would be very easy. It makes sense especially with palette files, because it is not that easy to sort out what will be the index when loaded to GLVis.

@justinlaughlin, can you resolve the conflicts?

[justinlaughlin]

Updated to branch off of #335 ; I added script/stream commands. ping @najlkin @tzanio

To test the script I ran this script with mesh/solution generated from a mfem example

solution refined.mesh sol.gf
palette_file share/palettes-crameri.txt
palette_name batlow

To test the stream I modified capacitor.saved and added this at the end

palette_file share/palettes-crameri.txt
palette_name batlow

A rather tangential, but also when you change the palette, the number that is shown is off by one compared to the list 🫣 .

Everything seems to work! 🤩

[najlkin]

Looks good! 🎉 Pls mention it in changelog.

Ahh, I do not like that "palettes", that "palette_file" was better in my opinion 😛 I do not think that there must be consistency with command line parameters. This is rather confusing, because "palette" command takes the index and "palettes" a file 🤪 .
