Patterns and Hatch Styles

When using gr_fillarea(), GR.fillarea or gr.fillarea(), you can not only fill the area with a solid color or draw its boundary, you can also use one of the following patterns or hatch styles. To do so, you need to set the interior fill style (e.g. with gr.setfillintstyle()) to INTSTYLE_PATTERN (2) or INTSTYLE_HATCH (3). You can then select a pattern or hatch style using gr.setfillstyle() and its index.
