We need paletted versions of the following textures:
- TM_BACK.png
- TM_PALM2.png
- TM_PALM3.png

(TM_PALM1.png degrades acceptably to paletted colors, so it's okay.)

These three textures become unforgivably ugly in the Doom palette (including the slightly tweaked ZDCMP2 palette).

Note that paletted version can be anything actually. It doesn't have to be the original processed through Photoshop's gradient map magic until they fit the palette. It just needs to be something with the same physical dimensions that will look okay in the ZDCMP2 palette.

Because said textures will get paletted anyway I'd also suggest converting them to doom graphic format, that way we can save filesize as doom graphic format textures compress better.

PNG compress less well in the PK3 because they're already compressed. (Especially after running PNGOUT and DeflOpt on them.)

I know that. Guess you can first run them through doom graphic format to filter out the redundant colors and export them as png. I think that way you'll get maximum compression.

Compression doesn't work that way. Besides, the PALVERS version has to be in palette anyway.
