 a spec like svg and you want other human beings to use it correctly
 \, make it clear and easy to use. Then go get a coffee and rewrite
 your incomprehensible \, ill-considered draft to actually make the
 documentation equally clear. Otherwise that part of the spec will be
 prone to errors and confusion \, from the backend to the wrapper libraries.

+#X text 524 147 It turns out trigonometry is difficult to grasp and
 just as hard to explain. This example is ported from Raphael's polar
 clock \, which draws an arc that follows the circumference of a circle.
 The original code is left uncommented \, causing more than one question
 on the internet equivalent to \, "how the heck does this thing work?".

 revealed both an error in tkpath's calculations for the arc's bounding
 box \, and an error somewhere in the drawing routine that causes the
 "jitter" from 3 to 6 o'clock in the animation.;

 #X text 524 480 This is just a partial port from Raphael. For example
 \, drawing commands don't support the easing style. I'm just using
 [line] \, but it's not hard to build a wrapper. (See easing.pd for
-an example.);
