Blit flags

Definition

Blit flags are bit flags which can be passed to some map functions, to specify a certain effect when blitting a graphic. These functions are:

• xput()
• map_xput()
• map_xputnp()

They can also be used to specify a certain effect for the blitting of the graphic of a process, by assigning blit flags to its local variable flags.
