FLI,FLC  -  Animations compressed by various RLE methods.

Notes:

N - No compression.
R - RLE (RunLength Encoded) compression, there are many types of
      RLE compression, nearly every format uses a different type.
P - PackBits compression, uses type RLE compression.
Z - LZW (Lempel-Ziv-Welche) compression, very good compression ratio.
L - Lossy compression, the best ratio, but does not preserve every bit.
D - Deflating compression, very good compression ratio.

r - PictureViewer only reads these files.
W - PictureViewer reads and writes these files.
w - PictureViewer only writes to these files.
+ - This format exists, but PictureViewer cannot read or write it.
- - This format does not exist.
? - Existence of this format is unknown to the author of PictureViewer.

*)   CDR, CDT, CMX and PAT are vector file formats, PictView reads a preview
       and imported bitmaps attached to every CDR, CDT, CMX and PAT files.
**)  ICN is not an official file format, but an image format of RIPterm.
***) JMX is not official file format, it is a format of the Tetris game.
*))  JPG can be 256colors (grayscales only), 24bit RGB,YCbCr,YIQ and
       32bit CMYK.
**)) SAM is not an official file format, but a format of AmiPro
documents.
