<p>This function draws a rectangle using the current source material to
texture or fill with. As a material may contain multiple texture layers
this interface lets you supply texture coordinates for each layer of the
material.</p>
<p>The first pair of coordinates are for the first layer (with the smallest
layer index) and if you supply less texture coordinates than there are
layers in the current source material then default texture coordinates
(0.0, 0.0, 1.0, 1.0) are generated.</p>
