Anticlockwise arcs from 0 to 2π are not rendered.

Browsers implement this by drawing a full circle.

Can't find info on the Canvas spec on this kind of values. Note that going from 0 to 2π in a anticlockwise direction is strange because:

• startAngle should be greater than endAngle
• adding 2π to startAngle would result in a 2π to 2π arc => Zero extent
• subtracting 2π from endAngle would result in a 0 to 0 arc => Zero extent

This is clearly a special case. So, are -4π, -2π, 4π also special cases ?

Add a reference / example with angles going toward 2π and further.
