But a lookup table mechanism for textures already exists in the BSP
format. If you just use the mipmaps lump with dummy textures (textures
with a name like WALL54_0 and an implied index by their position in the
lump, but a size of 0x0 and no actual texture data) then a utility program
can go through and replace all dummy textures with real textures from the
quake BSP files based on the names of the dummy textures. There is no need
to clutter up the entities lump with redundant data.
