NAME

       fli_pal_dirty_from,  fli_pal_dirty_to  - Indicate which parts of the palette have changed.
       Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       extern int fli_pal_dirty_from;

       extern int fli_pal_dirty_to;

DESCRIPTION

       These variables are set by next_fli_frame() to indicate which part of the fli_palette  has
       changed  since  the  last  call to reset_fli_variables(). If fli_pal_dirty_from is greater
       than fli_pal_dirty_to, the palette has not changed, otherwise colors fli_pal_dirty_from to
       fli_pal_dirty_to  (inclusive)  have  altered. You can use these when updating the hardware
       palette, to avoid unnecessary calls to set_palette(). Example:

          if (fli_pal_dirty_from <= fli_pal_dirty_to)
             set_palette_range(fli_palette, fli_pal_dirty_from,
                               fli_pal_dirty_to, 1);
