PM has a severely restricted palette. 
GIF files come with there own palette. 
A gif displayer in PM must map the GIF palette to the 
pre-selected palette of PM. 
This causes some distortion. 
 
OS/2 1.2 is advertised to allow an application to select 
a logical palette. 

OS/2 1.1 PM allows  256 colors in BGA 8514 mode.
and OS/2 1.1 PM allows  16 colors in VGA      
mode.
