<title>Description</title>
<para>fill(X,Y,C) displays 2D filled m-vertices polygons. When C is a
vector then C(i) gives the value for polygon i. The actual color is
computed by mapping the minimum and maximum value of C to the RBG colormap
of the current figure. The actual scale can be controlled by the 'caxis'
property.</para>
<para>When X,Y and C are matrices of the same size, the color is given by
the first vertex of each polygon or interpolated, depending on the
'shading' property.</para>
