NAME
       set_palette_range - Sets a specific range of the palette. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void set_palette_range(const PALETTE p, int from, int to, int vsync);

DESCRIPTION
       Sets the palette entries between from and to (inclusive: pass 0 and 255 to set the entire palette). If vsync is set it waits for the verti-

	  PALETTE palette;
	  ...
	  /* Modify the first 16 entries. */
	  change_first_16_colors(palette);
	  /* Now update them waiting for vsync. */
	  set_palette_range(palette, 0, 15, 1);
