Subpart texture file path

[Orion Pobursky]

Just to be clear here, when s/123.dat references a texture, it needs to do so using s/123.png as the texture name (just like s/123.dat would use s/123a.dat to reference a separate subpart). Given that, then parts/textures/s/123.png would be where the texture file would go.

Yes except that the png filename will be the one referenced in the !TEXMAP START|NEXT statement.
