Fix invalid pdf when using certain sizes of
dashed ellipse in pic.
* src/devices/gropdf/gropdf.pl: For short dashes on flat part
of ellipse some v. small numbers written in form n.nnnE-n which
is invalid for pdfs. Also rather than split each arc always into
4 pieces, split into number of quadrants described between start
and end angle. If arc describes a straight line, use line segment
rather than bezier curve. (grops does this as well)

Thanks to Morten Bo Johansen for reporting this issue.
The problem reported for dotted ellipses could not be reproduced, and the dots
are much easier to see if you include the command "linethick=2" in the
picture.
Although this bug is now closed, and I hate maths, I will be opening a new bug
since when dashed ellipses are very large the dashes are irregular, grops and
gropdf show identical irregularity so I suspect it is a problem in pic.
