                 Specifies an array of rectangles.

       shape     Specifies  a shape that helps the server to improve performance.  You can pass Complex, Convex,
                 or Nonconvex.

       width
       height    Specify the width and height, which are the dimensions of the rectangle to  be  filled  or  the
                 major and minor axes of the arc.

       x
       y         Specify  the  x and y coordinates, which are relative to the origin of the drawable and specify
                 the upper-left corner of the rectangle.

DESCRIPTION

       The XFillRectangle and XFillRectangles functions fill the specified rectangle or rectangles as if a four-
       point FillPolygon protocol request were specified for each rectangle:

       [x,y] [x+width,y] [x+width,y+height] [x,y+height]

       Each function uses the x and y coordinates, width and height dimensions, and GC you specify.

       XFillRectangles  fills  the  rectangles  in  the  order  listed  in  the array.  For any given rectangle,
       XFillRectangle and XFillRectangles do not draw a pixel more than  once.   If  rectangles  intersect,  the
       intersecting pixels are drawn multiple times.

       Both  functions use these GC components: function, plane-mask, fill-style, subwindow-mode, clip-x-origin,
       clip-y-origin, and clip-mask.  They also use these GC mode-dependent components: foreground,  background,
       tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

       XFillRectangle and XFillRectangles can generate BadDrawable, BadGC, and BadMatch errors.

       XFillPolygon fills the region closed by the specified path.  The path is closed automatically if the last
       point in the list does not coincide with the first point.  XFillPolygon does not  draw  a  pixel  of  the
       region  more  than  once.   CoordModeOrigin  treats  all  coordinates  as  relative  to  the  origin, and
       CoordModePrevious treats all coordinates after the first as relative to the previous point.

       Depending on the specified shape, the following occurs:

       •    If shape is Complex, the path may self-intersect.  Note that contiguous  coincident  points  in  the
            path are not treated as self-intersection.

       •    If  shape  is  Convex, for every pair of points inside the polygon, the line segment connecting them
            does not intersect the path.  If known by the client, specifying Convex can improve performance.  If
            you specify Convex for a path that is not convex, the graphics results are undefined.

       •    If  shape  is  Nonconvex,  the path does not self-intersect, but the shape is not wholly convex.  If
            known by the client, specifying Nonconvex instead  of  Complex  may  improve  performance.   If  you
            specify Nonconvex for a self-intersecting path, the graphics results are undefined.

       The fill-rule of the GC controls the filling behavior of self-intersecting polygons.

       This  function  uses  these  GC  components: function, plane-mask, fill-style, fill-rule, subwindow-mode,
       clip-x-origin,  clip-y-origin,  and  clip-mask.   It  also  uses  these  GC  mode-dependent   components:
       foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

       XFillPolygon can generate BadDrawable, BadGC, BadMatch, and BadValue errors.

       For  each arc, XFillArc or XFillArcs fills the region closed by the infinitely thin path described by the
       specified arc and, depending on the arc-mode specified  in  the  GC,  one  or  two  line  segments.   For
       ArcChord,  the  single  line  segment joining the endpoints of the arc is used.  For ArcPieSlice, the two
       line segments joining the endpoints of the arc with the center point are used.  XFillArcs fills the  arcs
       in  the  order  listed  in the array.  For any given arc, XFillArc and XFillArcs do not draw a pixel more
       than once.  If regions intersect, the intersecting pixels are drawn multiple times.

       Both functions use these GC components: function, plane-mask, fill-style, arc-mode, subwindow-mode, clip-
       x-origin,  clip-y-origin,  and  clip-mask.  They also use these GC mode-dependent components: foreground,
       background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

       XFillArc and XFillArcs can generate BadDrawable, BadGC, and BadMatch errors.

DIAGNOSTICS

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

       BadGC     A value for a GContext argument does not name a defined GContext.

       BadMatch  An InputOnly window is used as a Drawable.

       BadMatch  Some argument or pair of arguments has the correct type and range but fails to  match  in  some
                 other way required by the request.

       BadValue  Some  numeric  value  falls  outside  the  range  of  values accepted by the request.  Unless a
                 specific range is specified for an argument, the full range defined by the argument's  type  is
                 accepted.  Any argument defined as a set of alternatives can generate this error.
