Description:
------------
I experienced some unexpected results with the CLibPDF function: cpdf_fill_stroke() -> http://www.php.net/manual/en/function.cpdf-fill-stroke.php

According to the manual the function is able to fill the current path and then strokes the same path. As far is i am able to produce that function only fills and there is no stroking at all to see.

The code below is a convert from a C example from FastI/O (http://www.fastio.com/example/Arcs.c.txt)

Reproduce code:
---------------
$rbump = 0.1*100;
$xorig = 2.5*100;
$greenblue = 1.0;
$yorig = 7.5*10;
$radius= 2.2*100;

cpdf_setrgbcolor_stroke($cpdf, 0.7, 0.7, 0.0);

for($i=11; $i>=0; $i--) {
$radius -= $rbump;
$greenblue = $i/12.0;
cpdf_setrgbcolor_fill($cpdf, 1.0, $greenblue, $greenblue);
$eangle = ($i+1)*30.0;		/* end angle */
$sangle = 0.0;
cpdf_moveto($cpdf, $xorig, $yorig);
cpdf_arc($cpdf, $xorig, $yorig, $radius, $sangle, $eangle, 0);
cpdf_closepath($cpdf);
cpdf_fill_stroke($cpdf);	/* fill and stroke */
}

Expected result:
----------------
I expect to see: http://www.fastio.com/example/arctest.pdf

And then the "Color filled pie shapes" image. A red/white background with a green/yellow lines as pie pieces.

Actual result:
--------------
I actually see only the red/white background. No stroke lines are visable. I see the same result as when I only use cpdf_fill() function.

When I saw the source of the .pdf file generated by PHP there where some minor differences between a file which had cpdf_fill_stroke() and a file that used only cpdf_fill(). cpdf_fill_stroke() does add something to the .pdf file, but it's not visable in my PDF viewer (Adobe Acrobat 5.0).

To be short:
cpdf_fill_stroke() -> only fills (and does not stroke)
cpdf_fill() -> only fills
cpdf_stroke() -> only strokes
