I have installed ``dragon'' that recently appeared in comp.sources.x
on an HP9000/840, displaying on an HP9000/318 running HP's product X11
server.  The 318 is monochrome, but has window depth 8.  The following patch
was necessary to get dragon running:


*** orig/main.c	Tue May  2 17:35:29 1989
--- main.c	Tue May  2 17:57:11 1989

*** 169,176 ****
  {
      XImage ximage;
      Pixmap pix;
  
!     pix = XCreatePixmap( display, d, width, height, 1 );
      if (pix == (Pixmap)0) return (Pixmap)0;
  
      ximage.height = height;
--- 169,179 ----
  {
      XImage ximage;
      Pixmap pix;
+     XWindowAttributes wa;
+     
+     if (XGetWindowAttributes( display, d, &wa) == 0) return (Pixmap)0;
  
!     pix = XCreatePixmap( display, d, width, height, wa.depth );
      if (pix == (Pixmap)0) return (Pixmap)0;
  
      ximage.height = height;


However, there is still something wrong.  From reading the code, I
assume that the program should hilight selected tiles by calling
XFillPolygon with Xor_GC.  I don't get any hilight...  Also, I don't
get any numbers in the corners of the bam, dot or crak tiles.  The
other texts are visible.

An then, the game seems too simple... I mean, more or less randomly
selecting tiles to remove with no strategy I ``win'' every time.

Any clues?
