FLK format
----------
header:
  db 'FLK',26
  hxres dw ?
  hyres dw ?
  bpp db ?
  total dw 0    ;total (fix l8r)
  frame2 dd 0   ;frame 2 (fix l8r)
  spd dd 0      ;speed
  flgs db 0     ;no delta to 2nd frame included
  db 4 dup (0)  ;reserved

frame:
  size dd ?               ;size of data
  type db ?               ; 1=copy 2=RLE 3=Delta
  data db (size-1) dup ?  ;image data

COPY: strict copy
RLE: byte RLE compression
Delta: byte delta compression

In all three the Image is considered a 320x200 (or whatever) data stream so
compression bytes to not change when hitting a resolution boundry

PIX format
----------
header db 'PIC',26
  hxres dw ?
  hyres dw ?
  bpp db ?    ;bits / pixel
  flag db 0   ;not used
  comp db 0   ;compression  0=none 1=rle (2=lzh?-soon)
  db 5 dup (0)  ;reserved
;then 
;image = db hxres*hyres*bytes/pixel
