@ -1883,6 +1883,75 @@ the image onto the current drawable instead of the current image.
This function works just like imlib_render_image_on_drawable_skewed() except
you cannot skew an image (v_angle_x and v_angle_y are 0).

<pre><b><tt><font color="#660000"><font size=+2>void imlib_context_set_cliprect(int x, int y, int w, int h);</font></font></tt></b></pre>
<blockquote>
Sets the current clipping rectangle to (x,y w*h). The clipping rectangle
effects all image drawing functions and prevents the area outside the
rectangle from being edited. Set w to 0 to disable clipping.

A utility function to return clipped line coordinates.

<pre><b><tt><font color="#660000"><font size=+2>void imlib_polygon_new(void);</font></font></tt></b></pre>
<blockquote>
Returns a new polygon object with no points set.
</blockquote>
<pre><b><tt><font color="#660000"><font size=+2>void imlib_polygon_free(ImlibPolygon poly);</font></font></tt></b></pre>

Frees a polygon object.
</blockquote>
<pre><b><tt><font color="#660000"><font size=+2>void imlib_polygon_add_point(ImlibPolygon poly, int x, int y);</font></font></tt></b></pre>
<blockquote>
Adds the point (x,y) to a polygon object. The point will be added to the
end of the polygon's internal point list. The points are drawn in order,
from the first to the last.
</blockquote>
<pre><b><tt><font color="#660000"><font size=+2>void imlib_image_draw_polygon(ImlibPolygon poly, unsigned char closed);</font></font></tt></b></pre>
<blockquote>
Draws a polygon onto the current context image. Points which have been
added to the polygon are drawn in sequence, first to last. The final point will be
joined with the first point if <b>closed</b> is non-zero.
</blockquote>
<pre><b><tt><font color="#660000"><font size=+2>void imlib_image_fill_polygon(ImlibPolygon poly);</font></font></tt></b></pre>

Fill the area defined by the polygon on the current context image with
the current context colour.

<blockquote>
Calculate the bounding area of the polygon. (px1, py1) defines the upper
left corner of the bounding box and (px2, py2) defines it's lower right
corner.

Draw an ellipse on the current context image. The ellipse is defined as (x-xc)^2/a^2 + (y-yc)^2/b^2 = 1. This means that the point (<b>xc</b>,<b>yc</b>) marks the center of the ellipse, <b>a</b> defines the horizontal amplitude of the ellipse, and <b>b</b> defines the vertical amplitude.
