DESCRIPTION
       The XRecolorCursor function changes the color of the specified cursor, and if the cursor is being displayed on a screen, the change is vis-
       ible immediately.  The pixel members of the XColor structures are ignored; only the RGB values are used.

       XRecolorCursor can generate a BadCursor error.

       The XFreeCursor function deletes the association between the cursor resource ID and the specified cursor.  The cursor storage is freed when
       no other resource references it.  The specified cursor ID should not be referred to again.

       XFreeCursor can generate a BadCursor error.

       Some displays allow larger cursors than other displays.	The XQueryBestCursor function provides a way to find out what size cursors are
       actually possible on the display.  It returns the largest size that can be displayed.  Applications should be prepared to use smaller cur-
       sors on displays that cannot support large ones.

       XQueryBestCursor can generate a BadDrawable error.

DIAGNOSTICS
       BadCursor A value for a Cursor argument does not name a defined Cursor.

       BadDrawable
		 A value for a Drawable argument does not name a defined Window or Pixmap.
