- * DESCRIPTION:
- * This is the control's window procedure. Its purpose is to handle

- *
- * The special control messages for the gauge control are:
- *
- * ZYZG_SETRANGE : Sets the range of the gauge. In other
- * words, the number of parts that make a
- * whole.
- *
- * ZYZG_GETRANGE : Returns the current range of the gauge.
- *
- * ZYZG_SETORIENTATION : Sets the orientation of the gauge. This
- * can be one of the ZYZG_ORIENT_?? msgs.
- *
- * ZYZG_GETORIENTATION : Gets the current orientation of the
- * gauge.
- *
- * ZYZG_SETPOSITION : Sets the current position of the gauge.
- * In other words, how many pieces of the
- * whole have been used.
- *
- * ZYZG_GETPOSITION : Gets the current position of the gauge.
- *
- * ZYZG_SETDELTAPOS : Sets the position of the gauge +/- the
- * specified amount.
- *
- * ZYZG_SETFGCOLOR : Sets the foreground (percent done) color.
- *
- * ZYZG_GETFGCOLOR : Gets the foreground (percent done) color.
- *
- * ZYZG_SETBKCOLOR : Sets the background (percent not done)
- * color.
- *
- * ZYZG_GETBKCOLOR : Gets the background (percent not done)
- * color.
- *
- * WM_SETFONT : Sets the font to use for the percentage
- * text of the gauge.
- *
- * WM_GETFONT : Gets the current font in use by the
- * gauge.
