skin.c:
Rip out the pcx loading code and use LoadPCX instead. pcx.h: remove the data field from pcx_t: it was messing with gcc's idea of the structure size. also, update LoadPCX's prototype pcx.c: change LoadPCX to return tex_t (new type in texture.h) and take a new param: convert. LoadPCX will now wither load raw 8 bit or convert to rgba on loading depending on convert. Also, make LoadPCX WORK and use Hunk_TempAlloc to store the resulting texture. texture.h: define tex_t. defines an in-memory texture (either 8 or 32 bit, depending on the presense of a palette). Data comes immediately after the sturcture. eg tex_t *tex = Hunk_TempAlloc (sizeof (tex_t) + count)
