The binary DBC files for all expansions use the same field ordering
(VariationIndex=4, ColorIndex=5, Texture1=6), but classic/tbc/turtle
dbc_layouts.json had swapped texture and variation/color fields, causing
all skin/face/hair/underwear lookups to fail. Also adds generalized
NxN texture scaling and a second video to README.
11 original tracks in assets/Original Music/ now play on the login
screen and in thematically matched zones across Eastern Kingdoms and
Kalimdor. Added crossfadeToFile to MusicManager for local file
playback during zone transitions. New zones: Tirisfal, Undercity,
Barrens, STV, Duskwood, Burning Steppes, Searing Gorge, Ironforge,
Loch Modan, Orgrimmar, Durotar, Mulgore, Thunder Bluff, Darkshore,
Teldrassil, Darnassus.
