colormap changes

[Sean Kessler <smkessler us fortis com>]

  I am loading a bitmap file (microsoft .BMP) that contains 
  a 256 color palette and pixel data that represents indices
  into this palette (BI_RGB).  I created a GdkPixmap in which
  to display my bitmap.  I have been able to display the bitmap.
  However, not all of my colors are being displayed properly.
  I am first using ::gdk_window_get_colormap(..) to get the
  colormap.  Next, I set the entries in colormap->color to the
  entries in my loaded palette and call ::gdk_colormap_change(..).
  Next, I call ::gdk_gc_new(..) to create a copy of the GC of
  the display window (not sure if I have to do this but I do it).
  Finally, for every pixel in the bitmap I call ::gdk_gc_set_foreground(..)
  .... there MUST be a better way than calling this as it is pretty slow....
  and proceed to draw the point into the pixmap.  The pixmap gets
  displayed when configure_event fires.  Like I explained earlier,
  the bitmap (aside from being upside down, i'll take care of that
  later) does not appear to be mapped correctly into the GC and
  I'm not 100% sure how to accomplish this.  Any help would be
  greaty appreciated.  My apologies, I'm new to this stuff.
