//               Revision 1.6  2003/08/01 11:46:38  rherveille
//               1) Rewrote vga_fifo_dc. It now uses gray codes and a more elaborate anti-metastability scheme.
//               2) Changed top level and pixel generator to reflect changes in the fifo.
//               3) Changed a bug in vga_fifo.
//               4) Changed pixel generator and wishbone master to reflect changes.
//
//               Revision 1.5  2003/05/07 09:48:54  rherveille
//               Fixed some Wishbone RevB.3 related bugs.
//               Changed layout of the core. Blocks are located more logically now.
//               Started work on a dual clocked/double edge 12bit output. Commonly used by external devices like DVI transmitters.
//
//               Revision 1.4  2002/02/07 05:42:10  rherveille
//               Fixed some bugs discovered by modified testbench
//               Removed / Changed some strange logic constructions
//               Started work on hardware cursor support (not finished yet)
//               Changed top-level name to vga_enh_top.v
