- Consolidate psky* arrays into a "typedef struct psky_t" "g_psky" and "multipsky[]". - Factor out getting parallaxed sky properties into getpsky(). - Condense initial multi-psky setup by memcpy'ing from multipsky[]. - New function: MultiPsky_TileToIdx(). - Add new define PSKYOFF_MAX and related consistency-checking assertions. - Lower MAXPSKYTILES to 8 to reflect current usage (was 256). - Game: make multi-pskies consider dynamically-remapped MOONSKY1, BIGORBIT1 and LA. (Not very useful as the editor will still only act for the static values -- 80, 84 and 89, respectively.) An attempt has been made to preserve behavior even in strange cases, so this commit is unlikely to introduce regressions. Because of point 6, BYTEVERSION had to be bumped. git-svn-id: https://svn.eduke32.com/eduke32@3975 1a8010ca-5511-0410-912e-c29ae57300e0
