<p><tt>A Cairo backend for matplotlib implemented using pycairo<br>
Author: Steve Chaplin<br>
<br>
Cairo is a vector graphics library with cross-device output support.<br>
Features of Cairo:<br>
* anti-aliasing<br>
* alpha channel <br>
* in-memory image buffers<br>
* save image files:<br>
- PNG<br>
- PostScript (50% complete)<br>
- PDF (proposed, 0% complete)<br>

Requires (in order, all available from Cairo website):<br>
libpixman, cairo, pycairo<br>
<br>
cairo, pycairo from cvs fom Nov 06 2004 onwards are required<br>

draw many line segments with similar properties, it is faster<br>
to avoid the overhead of all the object creation etc. The<br>
lack of total configurability is compensated for with<br>
efficiency. Hence we don't use a GC and many of the line<br>

details<br>
<br>
sements is a sequence of ( line0, line1, line2), where linen =<br>
(x0, y0), (x1, y1), ... (xm, ym). Each line can be a<br>

transform is used to Transform the lines<br>

clipbox is a xmin, ymin, width, height clip rect<br>
<br>
colors is a tuple of RGBA tuples<br>
<br>
linewidths is a tuple of linewidths<br>
<br>
antialiseds is a tuple of ones or zeros indicating whether the<br>
segment should be aa or not<br>
<br>
offsets, if not None, is a list of x,y offsets to translate<br>
the lines by after transoff is used to transform the offset<br>
coords<br>

This function is intended to be overridden by the backend<br>
level in extension code for backends that want fast line<br>
